Show HN: Sourcebot – Self-hosted Perplexity for your codebase https://ift.tt/8nY9gHZ

Show HN: Sourcebot – Self-hosted Perplexity for your codebase Hi HN, We’re Brendan and Michael, the creators of Sourcebot ( https://ift.tt/vAswiYm ), a self-hosted code understanding tool for large codebases. We originally launched on HN 9 months ago with code search ( https://ift.tt/zsnME9D ), and we’re excited to share our newest feature: Ask Sourcebot. Ask Sourcebot is an agentic search tool that lets you ask complex questions about your entire codebase in natural language, and returns a structured response with inline citations back to your code. Some types of questions you might ask: - “How does authentication work in this codebase? What library is being used? What providers can a user log in with?” ( https://ift.tt/kLzMHxI ) - “When should I use channels vs. mutexes in go? Find real usages of both and include them in your answer” ( https://ift.tt/v2b4fQD ) - “How are shards laid out in memory in the Zoekt code search engine?” ( https://ift.tt/QTP0xyf ) - "How do I call C from Rust?" ( https://ift.tt/kjoVtqO ) You can try it yourself here on our demo site ( https://ift.tt/qX5MTf2 ) or checkout our demo video ( https://youtu.be/olc2lyUeB-Q ). How is this any different from existing tools like Cursor or Claude code? - Sourcebot solely focuses on code understanding . We believe that, more than ever, the main bottleneck development teams face is not writing code, it’s acquiring the necessary context to make quality changes that are cohesive within the wider codebase. This is true regardless if the author is a human or an LLM. - As opposed to being in your IDE or terminal, Sourcebot is a web app. This allows us to play to the strengths of the web: rich UX and ubiquitous access. We put a ton of work into taking the best parts of IDEs (code navigation, file explorer, syntax highlighting) and packaging them with a custom UX (rich Markdown rendering, inline citations, @ mentions) that is easily shareable between team members. - Sourcebot can maintain an up-to date index of thousands of repos hosted on GitHub, GitLab, Bitbucket, Gerrit, and other hosts. This allows you to ask questions about repositories without checking them out locally. This is especially helpful when ramping up on unfamiliar parts of the codebase or working with systems that are typically spread across multiple repositories, e.g., micro services. - You can BYOK (Bring Your Own API Key) to any supported reasoning model. We currently support 11 different model providers (like Amazon Bedrock and Google Vertex), and plan to add more. - Sourcebot is self-hosted, fair source, and free to use. Under the hood, we expose our existing regular expression search, code navigation, and file reading APIs to a LLM as tool calls. We instruct the LLM via a system prompt to gather the necessary context via these tools to sufficiently answer the users question, and then to provide a concise, structured response. This includes inline citations, which are just structured data that the LLM can embed into it’s response and can then be identified on the client and rendered appropriately. We built this on some amazing libraries like the Vercel AI SDK v5, CodeMirror, react-markdown, and Slate.js, among others. This architecture is intentionally simple. We decided not to introduce any additional techniques like vector embeddings, multi-agent graphs, etc. since we wanted to push the limits of what we could do with what we had on hand. We plan on revisiting our approach as we get user feedback on what works (and what doesn’t). We are really excited about pushing the envelope of code understanding. Give it a try: https://ift.tt/NWHyfLI . Cheers! https://ift.tt/6YO23gx July 30, 2025 at 08:14PM

Show HN: I use AI to send myself personalized weekly recaps from my saved links https://ift.tt/nAvtwRI

Show HN: I use AI to send myself personalized weekly recaps from my saved links Sharing something that I’ve been working on: I made a save-later app for all my bookmarks. I save links throughout the week and, every Sunday morning, the app sends me a personalized recap with: -patterns and themes that connect my week to my broader interests -a nudge toward links I saved but never revisited -one reflective question to help me decide what else might be worth exploring I was inspired by older read-later apps like Instapaper. I wanted to make something minimalist, so it’s just a simple feed of your links (with tags and annotations linked to each link) and it is set up to ingest all kinds of content, not just text. I also did want it to be bloated as the full-fat AI stuff you see recently. So this is a simpler and more proactive take on the concept of a bookmarking app. Imagine if Pocket and Spotify Wrapped had a baby. I also personally enjoy using the chat to find links across subjects and sources with context, like “Show me the 5 links on travel i’ve returned to the most” or “all recipes with porcini mushrooms” or “show me everything on Topic X i’ve made the most notes on.” I’ve posted about this on HN before, always had great feedback. Happy to answer any questions. (I’m not technical, I'm a writer/ filmmaker.) https://tryeyeball.com/ July 31, 2025 at 04:38AM

Show HN: State of the Art Open-source alternative to ChatGPT Agents for browsing https://ift.tt/c6Ngjwb

Show HN: State of the Art Open-source alternative to ChatGPT Agents for browsing Hey HN, We are Winston, Edward, and James, and we built Meka Agent, an open-source framework that lets vision-based LLMs execute tasks directly on a computer, just like a person would. Backstory: In the last few months, we've been building computer-use agents that have been used by various teams for QA testing, but realized that the underlying browsing frameworks aren't quite good enough yet. As such, we've been working on a browsing agent. We achieved 72.7% on WebArena compared to the previous state of the art set by OpenAI's new ChatGPT agent at 65.4%. You can read more about it here: https://ift.tt/xLI9sdT . Today, we are open sourcing Meka, our state of the art agent, to allow anyone to build their own powerful, vision-based agents from scratch. We provide the groundwork for the hard parts, so you don't have to: * True vision-based control: Meka doesn't just read HTML. It looks at the screen, identifies interactive elements, and decides where to click, type, and scroll. * Full computer access: It's not sandboxed in a browser. Meka operates with OS-level controls, allowing it to handle system dialogues, file uploads, and other interactions that browser-only automation tools can't. * Extensible by design: We've made it easy to plug in your own LLMs and computer providers. * State-of-the-art performance: 72.7% on WebArena Our goal is to enable developers to create repeatable, robust tasks on any computer just by prompting an agent, without worrying about the implementation details. We’d love to get your feedback on how this tool could fit into your automation workflows. Try it out and let us know what you think. You can find the repo on GitHub and get started quickly with our hosted platform, https://ift.tt/PQNtHwh . Thanks, Winston, Edward, and James https://ift.tt/jw15LcA July 30, 2025 at 07:41PM

Show HN: No Hype AI – get oriented in using LLM tools for software engineering https://ift.tt/BmkuwlW

Show HN: No Hype AI – get oriented in using LLM tools for software engineering Hey HN! When I started looking into LLMs and agents for software development and introducing them at work, I quickly realised that a person new to the topic faces a real barrage: - all the hype (AGI, engineers getting replaced by AI etc.) - conflicting opinions in virtually every discussion—for every person saying they’ve 10x-ed their productivity, there is a comment decrying LLMs as an utter failure - a lot of jargon (MoE, MCP, RAG, distillation, quantisation etc. etc.) - a profusion of models, IDEs/IDE extensions, CLI agents, other tools etc. Sorting through all of this can be quite tricky for somebody coming in fresh! HN users have been discussing LLM tools for a long time of course, but many programmers I know still haven’t _really_ tried anything other than an LLM web UI and haven't been following the progress of tools much. So my goal for this project was to provide a balanced overview of the topic, point people to substantive resources on eg. context management and productivity effects, and cover the concerns and risks as well (from prompt injection to shady training data sourcing). I hope it's useful! https://nohypeai.dev July 28, 2025 at 01:09AM

Show HN: Flyde 1.0 – Like n8n, but in your codebase https://ift.tt/L270Syc

Show HN: Flyde 1.0 – Like n8n, but in your codebase Hi HN! I'm excited to share Flyde 1.0. A big update to the open-source visual programming tool I launched here in March of last year ( https://ift.tt/6Q9Avz5 ). Since Flyde’s launch, there's been a huge rise in demand for visual builders, especially for AI-heavy workflows. Visual-programming shines with async and concurrency-heavy logic, which describes most LLM chains perfectly. A few months ago, I tried to capitalize on this trend by launching a commercial version of Flyde called Flowcode ( https://ift.tt/TjhlVZp ). It didn't go well. I learned the hard way that Flyde’s strength wasn't just about flexibility or performance compared to tools like n8n. The real value was always how Flyde fits inside your existing codebase . The launch also helped me understand that there's still a big gap: no tool really covers the full lifecycle, from rapid prototyping to deep integration, evaluation, and iteration inside your own projects. So, over the last few months, I worked hard to polish Flyde: - Cleaned up and simplified the nodes API - Made it possible to fork any node for maximum flexibility - Launched a new online playground for quick experimenting and sharing ( https://ift.tt/cKjJ0p5 ) - Created a new CLI tool to speed up development and setup - Fixed a ton of bugs - Simplified the UI/UX to make it smoother and less confusing There’s still a lot of missing stuff. Better templates, docs, and nodes, but I think it’s finally stable and useful enough to give it another shot. My plan is to first make sure that Flyde is usable and valuable as an OS project, and then try to provide additional value via “Flyde Studio” - a SaaS that will help non-engineers iterate on Flyde flows from a web-app. Changes become a PR in the host repo. I'd really love some honest feedback and hear whether Flyde resonates with an existing pain/problem. Check it out here: Playground: https://ift.tt/cKjJ0p5 GitHub: https://ift.tt/TCrWKV3 Looking forward to hearing your thoughts! - Gabriel https://ift.tt/TCrWKV3 July 27, 2025 at 11:46PM

Show HN: LogMerge – View multiple log files in a merged view Hey HN! I needed a tool to view multiple log files in a merged view, and easily filter based on the specified fields. Spent a good amount of time searching, but couldn’t find any open source tool that quite did what I wanted. So, ended up building a custom solution instead (I would appreciate suggestions on tools that have similar functionality). I don't know much about GUIs (most all my PC based utilities are CLI) - but I did have the following: - I know enough Python to spot obviously wrong things - Some knowledge of how to make programs performant in general - ... and tokens to burn :) GitHub : https://ift.tt/q5zQecR Usage Video: https://youtu.be/37V_kZO2TLA Key Features: - Merge and display multiple log files in a single, chronologically ordered view - Live log monitoring with auto-scroll - Add files individually or discover them recursively with regex filtering - Plugin-based system to support any log format (easy to extend!) - Filtering: discrete values, numeric ranges, regex/text, and time-based queries - Color-coded file identification - Configurable columns and ordering - Built-in plugins for syslog, CANKing (CAN Bus monitoring tool), and another custom log format called dbglog.

Show HN: Price Per Token – LLM API Pricing Data The LLM providers are constantly adding new models and updating their API prices. Anyone building AI applications knows that these prices are very important to their bottom line. The only place I am aware of is going to these provider's individual website pages to check the price per token. To solve this inconvenience I spent a few hours making pricepertoken.com which has the latest model's up-to-date prices all in one place.

Show HN: TheProtector – Linux Bash script for the paranoid admin on a budget https://ift.tt/Ij9Uo26

Show HN: TheProtector – Linux Bash script for the paranoid admin on a budget Hi HN, I spent the past year building this in my spare time because I got tired of enterprise security tools that cost $50K/year and don't understand Linux. TheProtector is a comprehensive security monitoring tool that actually runs on the systems we use (Linux) instead of being a Windows-first afterthought. Built it entirely on a $500 laptop because I believe good security shouldn't require unlimited budgets. Features: - Real-time process, network, and file monitoring - YARA malware detection with custom rules - eBPF kernel monitoring (when available) - Behavioral baseline establishment and anomaly detection - Active threat response (blocks IPs, kills processes, quarantines files) - Anti-evasion detection for rootkits and advanced threats - Honeypots for attack detection - Web dashboard for monitoring - Single bash script, no complex installation The tagline is "not perfect but better than most" because I'm tired of security vendors claiming their tools are flawless. This actually works, costs $0, and you can read every line of code. I know bash isn't the sexy choice for security tools, but it runs everywhere, has zero dependencies, and most Linux admins can read/modify it. Sometimes boring technology that works is better than fancy technology that doesn't. It's designed for the intersection of "paranoid about security" and "don't have enterprise budgets" - which describes most of us actually running Linux systems. GitHub: https://ift.tt/BA7UNv9 Been running it on my own systems for months. Catches the stuff that matters and doesn't flood you with false positives. If you hate expensive security theater as much as I do, might be worth a look. Open to feedback, especially from folks who know more about this stuff than I do. Thanks, IHATEGIVINGAUSERNAME (yes, I really do hate giving usernames) https://ift.tt/BA7UNv9 July 24, 2025 at 12:07AM

Show HN: Kafka, the first AI employee (NEW SOTA ON GAIA BY 20%) https://ift.tt/k2vgUEl

Show HN: Kafka, the first AI employee (NEW SOTA ON GAIA BY 20%) Hi HN, I'm Gokhan, the founder of Brainbase Labs. Today we're releasing an early preview of our first generalist agent, Kafka. Kafka is the first AI employee, he comes with his own computer as well as his own email, phone and Slack so you can work with him just like you would with a regular employee. You can forward him emails, give him a call, tag him on Slack. We built Kafka as the basis for our other AI employees we will be releasing over the coming months. Kafka currently achieves 77.2% on the GAIA Level 3 benchmark, getting us closer to human performance at 87%. We've achieved this by creating a new type of planning algorithm called "structured planning" which allows Kafka to run very long term plans without getting sidetracked or hallucinating. Kafka can do some cool things, he can push code to AWS, direct its own commercial using Veo3 and do actual production tasks on Upwork/Fiverr. We're very keen to hear what HN thinks about Kafka, and how we can improve. Appreciate any feedback! https://ift.tt/7oEhJ4w July 23, 2025 at 10:21PM

Show HN: Compass CNC – Open-Source Handheld CNC Router https://ift.tt/HUNPlje

Show HN: Compass CNC – Open-Source Handheld CNC Router Hey HN, I am Cam, and for the past two years I have been working on Compass, an open-source handheld CNC router that brings computer precision to woodworking while keeping the user directly involved in the process. The idea started as my senior design project at UC Berkeley, with the goal of making a more approachable CNC machine—standard CNC machines are expensive, bulky, and remove you from the tactile “maker” experience. Compass solves that by combining a handheld router with real-time robotic assistance. You move the router roughly along a design path, and Compass uses four optical flow sensors (like in computer mice) and a 3-axis motion system to auto-correct for precision cuts. What is different about Compass: - Open source: All plans, firmware, and CAD files are available on GitHub. - Affordable: The DIY build costs ~$600 in parts, and I am selling kits for <$800. - No external markers: The sensing technology allows for positioning without external markers, so no setup or consumables required. - Portable: Fits in a backpack and is not limited by a fixed work envelope. We recently completed our first beta program and have just launched V1 kits for pre-order. You can find more info and the launch video at the listed URL.

Show HN: An API for human-powered browser tasks https://ift.tt/z6AIJEd

Show HN: An API for human-powered browser tasks At APM Help, we have a large team that performs repetitive, browser-based tasks. Years ago, to manage this work securely and get a clear audit trail, we built an internal platform we call "Hub." It's essentially a locked-down environment where our team works that records their sessions, tracks every interaction, and prevents data from being copied or shared. It's been our internal source of truth for years. More recently, like many companies, we've been building more automation. And like everyone else, we've seen our automations fail on edge cases—a weirdly formatted invoice our parser can't read, a website layout change that breaks a scraper, etc. Our team would have to manually step in to fix these. We realized other developers must have this exact same problem, but without a 250-person team on standby. So we connected our old, battle-tested Hub to a new, modern front door: a Human-in-the-Loop (HITL) API. We're calling it browser-work.com. The idea is simple: when you hit a task that needs a human, you can send it to our team through the API. Here's how it works: - You POST a request to our endpoint. The payload contains the context for the task (like a URL) and a set of instructions for the human on what to do. - The task appears in the Hub, where one of our trained operators can claim it. - They perform the task exactly as instructed, all within the secure Hub environment. - When they're done, we send a webhook to your system. The return payload includes the task's output, any notes left by the human, and a detailed log of their actions (e.g., DOM elements they interacted with). For example, if your automation for paying a utility bill fails, you can pass the task to us. A person will log in, navigate the portal, make the payment, and return a confirmation number. The product is live and we're looking for people with interesting use cases. I'm Robert, the CIO. If this sounds useful to you, send me a brief email about your use case at robert@apmhelp.com and we can get you started right away. Happy to answer any questions here. https://ift.tt/HyCMRmr July 21, 2025 at 09:46PM

Show HN: The missing link of a bookstore's tech stack https://ift.tt/r0VtRMO

Show HN: The missing link of a bookstore's tech stack Hi HN! I built Bookhead because I used to work as a bookseller and I wasn't happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick & mortar). So I decided to make my own bookselling app...a classic hacker distraction. Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their online brand I have a very exciting roadmap that I'm not ready to fully reveal, but it's all based on books. I'm building a sorta Zapier-like platform for independent booksellers. Everything is so fragmented and disconnected, which makes it hard for booksellers to do their work. I'm hoping to change that. I have a blog post that lays out my vision here: https://ift.tt/4uw15jT The current iteration is like "data engineering as a service for books." A book is a powerful thing. I'm hoping to give a bookstore everything they need to sell books online. Inventory, e-commerce, marketing, etc. It's a crowded market but I've had fun making the bookselling app that I believe should exist. If you know any booksellers, please let them know about this! I'm onboarding my first customer right now and the biggest bottleneck is the other bookselling software providers, despite my intention to collaborate instead of compete. It's frustrating to wait for two weeks for a point of sale provider to setup an integration. It's almost like they don't care about their customers. Some providers even require ethernet cables for their software...still partying like it's 1999. Perfect for early-adopter booksellers frustrated with current tech who understand the power of automation. I'm currently looking for funding so I can focus on this full-time. My biggest problem right now is time (aka money) because I have to sell my time to make rent etc, and can't focus on this project like I need to. I've gotten good validation from booksellers and other technically savvy folks in the industry (I've heard from two different companies that they've considered building something like this), so I believe I have something valuable. I'm not interested in funding from somebody who doesn't share my love for books or doesn't support my mission: help people use technology to promote literature. I believe that literature is one of humanity’s most prized creations, and we can use technology as a tool to keep this gift alive. Please email me at sam@bookhead.net if you know of booksellers who might want to be an early adopter, or know of any funding opportunities that might be a good fit. https://bookhead.net/ July 21, 2025 at 12:19AM

Show HN: Transform passive YouTube watching into active learning https://ift.tt/KLeBfvJ

Show HN: Transform passive YouTube watching into active learning I've been self-learning from YouTube for years—everything from coding to design to business skills. But I kept hitting the same wall: YouTube learning has no structure. Your knowledge gets scattered across random playlists, you're passively consuming content without real retention, and when you're confused, there's nobody to ask. I built Notetube to fix this by layering organizational tools with AI to create a proper learning system: Organizational layer: Build structured collections by topic/course/skill, visualize your learning progress with dashboards, create and track your learning goals AI layer: Automatically generates detailed notes (3000+ words for 1 hour of content) and summaries, identifies key moments with timestamps, creates personalized quizzes for retention testing, and provides a chat interface for instant help when concepts aren't clear ...plus additional features like timestamped note-taking, but I'll keep this brief.

Show HN: I built library management app for those who outgrew spreadsheets https://ift.tt/v0bBrya

Show HN: I built library management app for those who outgrew spreadsheets I've been working on librari.io for the past several months and just launched the beta version. The Problem: I have 500+ books across multiple rooms in my house and was desperately looking for an app to manage them properly. Most library management apps are either too basic or designed for institutional libraries with rigid workflows that don't fit personal use. What I Built: - Multiple libraries: manage collections in different locations - Location tracking - remember exactly which shelf each book is on - Loan management - track books you've lent to friends - Custom fields & tags - store any additional book info the way YOU think about them - Reading progress tracking - dates, duration, personal ratings - Modern UI/UX - clean & actually enjoyable to use Current Status: - Beta version live - Working on improving the responsiveness of the app and addressing initial user feedback Would love feedback! Especially curious about: - What features would make YOU actually use a library management app? - UI/UX feedback always welcome - Any book collectors here who'd be interested in beta testing? Looking forward to your thoughts! Thank you in advance. https://www.librari.io/ July 19, 2025 at 12:58AM

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG https://ift.tt/OjNTbXq

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG For folks working on Graph RAG and trying to get LLMs to generate Cypher queries, I ran some experiments on the LDBC dataset and wrote a blog post about it (code is available in the link shown at the end of the post). I've been trying to answer a burning question of mine that I've had for a while now: when doing Text2Cypher, are LLMs better at interpreting graph schemas in JSON, XML or YAML? (Spoiler alert, the format barely matters, it's all to do with context engineering and retaining only the relevant parts of the graph schema in the prompt). Results on the latest LLMs are really good! The post also contains some other tips on graph schema design: I think we're in an age now where we need to design graph schema for both LLMs and humans. If you're working on Text2Cypher in any way, hope some of these ideas and experiments are useful! https://ift.tt/xaVztdb July 18, 2025 at 07:22PM

Show HN: I built a 2B-page search engine, independent of Google/Bing https://ift.tt/oZSeqlA

Show HN: I built a 2B-page search engine, independent of Google/Bing Hi HN, For the last 18 months, I've been working solo on building a completely independent search engine from scratch. Today, I'm opening it up for beta testing and would love to get your feedback. The project powers two public sites from the same 2-billion-page index: Searcha.Page: A session-aware search engine that uses a persistent browser key (not a cookie) for better context. Seek.Ninja: A 100% stateless, privacy-first version with no identifiers at all. The entire stack is self-hosted on a single ~$4k bare-metal EPYC server in my laundry room (no cloud, no VC funding). The search pipeline is a hybrid model, using a traditional lexical index for the heavy lifting and lightweight LLMs for specific tasks like query expansion and re-ranking. It's an experiment in capital efficiency and digital sovereignty—proving you don't need Big Tech APIs to compete. I’m looking for feedback on search result relevance, speed, and the clarity of the privacy models. Please try it out and let me know what you think.

Show HN: A 'Choose Your Own Adventure' Written in Emacs Org Mode https://ift.tt/xXSfKHA

Show HN: A 'Choose Your Own Adventure' Written in Emacs Org Mode I authored and developed an interactive children's book about entrepreneurship and money management. The journey started with Twinery, the open-source tool for making interactive fiction, discovered right here on HN. The tool kindled memories of reading CYOA style books when I was a kid, and I thought the format would be awesome for writing a story my kids could follow along, incorporating play money to learn about transactions as they occurred in the story. Twinery is a fantastic tool, and I used it to layout the story map. I really wanted to write the content of the story in Emacs and Org Mode however. Thankfully, Twinery provided the ability to write custom Story Formats that defined how a story was exported. I wrote a Story Format called Twiorg that would export the Twinery file to an Org file and then a Org export backend (ox-twee) to do the reverse. With these tools, I could go back and forth between Emacs and Twinery for authoring the story. The project snowballed and I ended up with the book in digital and physical book formats. The Web Book is created using another Org export backend. Ten Dollar Adventure: https://ift.tt/TFhSCt6 Sample the Web Book (one complete storyline/adventure): https://ift.tt/IkqVK4z I couldn't muster the effort to write a special org export backend for the physical books unfortunately and used a commercial editor to format these.

Show HN: Bedrock – An 8-bit computing system for running programs anywhere Hey everyone, this is my latest project. Bedrock is a lightweight program runtime: programs assemble down to a few kilobytes of bytecode that can run on any computer, console, or handheld. The runtime is tiny, it can be implemented from scratch in a few hours, and the I/O devices for accessing the keyboard, screen, networking, etc. can be added on as needed. I designed Bedrock to make it easier to maintain programs as a solo developer. It's deeply inspired by Uxn and PICO-8, but it makes significant departures from Uxn to provide more capabilities to programs and to be easier to implement. Let me know if you try it out or have any questions. https://ift.tt/Ur3gR9Z July 11, 2025 at 03:50AM

Show HN: StartupList EU – A public directory of European startups https://ift.tt/r0LZ5CN

Show HN: StartupList EU – A public directory of European startups I’m from Europe, and when I spent a summer at Stanford, I saw how different the startup ecosystem is in the US. Everything there feels connected. In Europe, it’s scattered. Hard to discover early-stage startups unless you’re in the right city or network. So I built StartupList EU, a public directory where anyone can list or browse European startups. The goals is to contribute to the EU startup ecosystem more accessible and transparent for founders, investors and operators. What it does: - Founders can submit their startup for free - Each profile includes data like team size, category, funding, revenues, location, founders and more - You can search by country, industry, name, team size, country and business model - It works across the whole EU, not just big hubs like Berlin or Paris Right now there are 34 startups listed. More are coming in daily. I’m working on better filters, API access, and a weekly newsletter. Would love your feedback: - What data would be most useful to you? - What would make this genuinely helpful for founders, investors, or researchers? - If you are from US, what's your take about EU startup ecosystem? https://ift.tt/zREZDS5 July 15, 2025 at 01:54AM

Show HN: I made a JSFiddle-style playground to test and share prompts fast I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a use-it-or-loose-it way. For a tool we use maybe 2–3 times per sprint. That’s just ridiculous! IMO, it should be something more like JSFiddle. A simple prompt playground that does not require you to signup, does not require API keys, and let's experiment instantly, i.e. you just enter a browser URL and start working. Like JSFiddle has. And mainly, something that costs me nothing if I'm or my team is not using it. Eventually I gave up looking for solution and decided to build it by myself. Here it is: https://langfa.st Help me find what's wrong or missing or does not work from you perspctive. P.S. I did not put any limits or restrictions yet, so test it wisely.

Show HN: I Built a Stick-On Wireless Lamp That Installs in 30 Seconds Hi HN! I recently built a simple, rechargeable wall lamp that doesn't require any tools, wires, or drilling. It sticks to surfaces using adhesive pads, rotates 360°, and charges via USB-C. The goal was to make lighting *super minimal, renter-friendly, and easy to install*. The idea came from personal frustration — I live in a rented apartment where I can’t drill holes, and I wanted a modern-looking light I could reposition easily. I know this isn’t a software product, but I figured some of you might appreciate the problem-solving side of it — designing minimal hardware that’s useful, elegant, and simple. Would love feedback on the product or the landing page: Happy to answer any questions about the design, battery, lighting specs, remote control logic, etc. Thanks! https://ift.tt/mT7QFO3 July 13, 2025 at 01:56AM

I’m the developer of Elara, a tool that automatically scans your code for security issues like misconfigurations, secrets, and risky packages, so you can focus on building without stressing about all this stuff. It’s designed to be simple and fast. I see so many people launching products online without even knowing what security risks they might have. If you’re a developer or into tech, you know how hard it is to keep systems safe. Yet shockingly it feels like nobody really cares. I want to help folks catch these issues early, before they get burned. Elara runs multiple security scanners simultaneously, aggregates the results into a single interface, and gives you an actionable to-do list to fix the problems. It’s super simple to try, just log in with GitHub and see for yourself. Would really appreciate your feedback! https://ift.tt/aKsL5hu July 12, 2025 at 09:50PM

Show HN: Transition – AI Triathlon Coach Hey HN, I’m Alex, a triathlete, dad, and software engineer. I’ve been building Transition — an app for triathletes that creates adaptive training plans based on your goals, schedule, and workout data (Garmin, Strava, etc). Most plans are static, which never really worked for me as a parent and someone with an unpredictable schedule. Transition adjusts every week using your actual workouts and progress, so the plan changes when you miss a session, set a new PR, or need to shift your priorities. I built this because nothing else was flexible enough for my life, and I’m curious if others have the same problem. It’s in beta and free to try. I’d love feedback from the HN crowd — especially around the training logic, onboarding, or any ways to make it more useful for real athletes.

Show HN: RULER – Easily apply RL to any agent https://ift.tt/CFnPHmD

Show HN: RULER – Easily apply RL to any agent Hey HN, Kyle here, one of the co-founders of OpenPipe. Reinforcement learning is one of the best techniques for making agents more reliable, and has been widely adopted by frontier labs. However, adoption in the outside community has been slow because it's so hard to implement. One of the biggest challenges when adapting RL to a new task is the need for a task-specific "reward function" (way of measuring success). This is often difficult to define, and requires either high-quality labeled data and/or significant domain expertise to generate. RULER is a drop-in reward function that works across different tasks without any of that complexity. It works by showing N trajectories to an LLM judge and asking it to rank them relative to each other. This sidesteps the calibration issues that plague most LLM-as-judge approaches. Combined with GRPO (which only cares about relative scores within groups), it just works (surprisingly well!). We have a full writeup on the blog, including results on 4 production tasks. On all 4 tasks, small Qwen 2.5 models trained with RULER+GRPO beat the best prompted frontier model, despite being significantly smaller and cheaper to run. Surprisingly, they even beat models trained with hand-crafted reward functions on 3/4 tasks! https://ift.tt/X3L0QIS Repo: https://ift.tt/GJ6Oc71 https://ift.tt/X3L0QIS July 11, 2025 at 11:17PM

Show HN: Open source alternative to Perplexity Comet https://ift.tt/JUT6mvS

Show HN: Open source alternative to Perplexity Comet Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://ift.tt/R1hMwkZ --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad company, so no weird incentives. Your data stays on your machine. You can use local LLMs with Ollama . We also support BYOK (bring your own keys), so no $200/month plans. Another big difference vs Perplexity Comet: our agent runs locally in your browser (not on their server). You can actually watch it click around and do stuff, which is pretty cool! Short demo here: https://bit.ly/browserOS-demo --- How we built? We patch Chromium's C++ source code with our changes, so we have the same security as Google Chrome. We also have an auto-updater for security patches and regular updates. Working with Chromium's 15M lines of C++ has been another fun adventure that I'm writing a blog post on. Cursor/VSCode breaks at this scale, so we're back to using grep to find stuff and make changes. Claude code works surprisingly well too. Building the binary takes ~3 hours on our M4 Max MacBook. --- Next? We're just 2 people with a lot of work ahead (Firefox started with 3 hackers, history rhymes!). But we strongly believe that a privacy-first browser with local LLM support is more important than ever – since agents will have access to so much sensitive data. Looking forward to any and all comments! https://ift.tt/yOrD54o July 10, 2025 at 11:03PM

Show HN: Stravu – Editable, multi-player AI notebooks with text, tables, diagram Hi HN! I'm Karl one of the co-founders of Stravu. ( https://stravu.com ) Using AI for work 24x7, we realized that four things would make AI more useful for us and a lot of other power users and teams: Editable output: AI gives output that is half right and our only option was to either keep chatting laboriously or copy it to a Google Doc. We made Stravu so you can edit what the AI says in chat or in an attached notebook. Everything editable. Approve AI changes: When AI makes a change to some text, you can't tell what changes. We put Red/Green diffs that you can approve into Stravu. Unify text, tables, diagrams: We were jumping between tools to work with AI on text, tables, diagrams, etc.. Just because Microsoft did that 30 years ago, doesn't mean it makes sense now. We made Stravu so you can work with AI across text, tables, diagrams, (and 2x2s, formulas, more soon) and have them inform each other. Actual multi-player team collab with AI: We couldn't collaborate as a team in AI (even with the ChatGPT Teams plan). We wanted to be able to chat with AI together as a team or see the changes AI was making in the canvas/notebook together and edit together. So we made Stravu support multi-player collaboration in every aspect... chats, notebooks, text, tables, diagrams..etc. Some of the use cases of our current Beta customers include: scrum teams doing feature/customer/competitive research and feature definition, account teams building vertical/geo/account plans, consultants and investment teams working on market/company analysis. We are currently in beta and actively iterating based on user feedback. Please try it out at: https://stravu.com We highly value your feedback! July 9, 2025 at 07:47PM

Show HN: OpenAPI mocks that don't suck – realistic test data, quick setup Hi HN! I'm Ankit, the founder of Beeceptor, a request mocking and intercepting tool. This time, I built something new to address a pain I’ve personally felt (and heard from dozens of QA, frontend, and platform teams): making OpenAPI specs actually useful during development. API contracts just sit around as docs often. What if you could 'activate' them, instantly have a realistic, hosted mock server-with contract validation, smart test data, and early usage? So I made _Mockaroo for OpenAPI_, but with brains. It spins up a hosted mock server from your spec in one click. It: - Generates sensible context-aware, test data using FakerJS (e.g., age returns realistic numbers, not 10000) - Validates incoming requests against your contract definition and returns detailed, actionable error messages. - Supports JSON, binary, CRUD style API responses. - Gives a HOSTed API server URL, that's ready in a few seconds. - Helps frontend teams start testing before the backend is ready - Gives QAs a place to play, verify and run performance tests. - Enables the best developer experience, requiring no account setup and a working mock API server for experiments, and API cost savings. No local setup, no writing custom mock rules, no fuss. Just activate your OpenAPI spec, and your API starts “working” in seconds. Besides, Beeceptor shows live request logs, where responses can be overridden. Quick demo: https://www.youtube.com/watch?v=2vUD_B3aw5I --- Would love your thoughts, feedback, or use cases I haven’t thought of yet. Happy to share more technical details if there's interest. Thanks for reading! https://ift.tt/lbNIG3Y July 9, 2025 at 01:00AM

Show HN: OffChess – 100k+ Offline, Ad-Free Chess Puzzles App https://ift.tt/dlrE9k1

Show HN: OffChess – 100k+ Offline, Ad-Free Chess Puzzles App Hi HN! I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet. Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess. OffChess is an iPhone/Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in 1/2/3/4/5, tactics like pins/forks/skewers, or openings like Sicilian/French, etc). You gain or lose points based on how you perform, so there's a light rating system to keep things engaging. No accounts, no tracking, no monthly subscriptions, no internet required. Just pure, old-school tactical chess training, wherever you are. You can check out the iPhone/iPad app at https://ift.tt/UAcrNLb... or the Android app at https://ift.tt/FQIW4nB Would love feedback, bug reports, or suggestions. Thanks! https://offchess.com July 8, 2025 at 02:27PM

Show HN: HireIndex – A Searchable Directory for Who Wants to Be Hired on HN https://ift.tt/4Itrdag

Show HN: HireIndex – A Searchable Directory for Who Wants to Be Hired on HN Hi HN, I built hireindex.xyz – a searchable website that aggregates and indexes candidates from the "Who Wants to Be Hired" threads on Hacker News. Coming soon: Analytics to highlight trends in skills, technologies, and candidate preferences across HN posts. With HireIndex, you can: Search by tech stack. Quickly scan bios, salary expectations, and contact links. Filter by remote/on-site preferences and employment type. I made this because I was tired of scrolling through long threads and wanted a better way to find interesting people. Would love your feedback – especially around UX and anything that would make it more useful to hiring managers, founders, or even job seekers themselves. https://hireindex.xyz https://hireindex.xyz July 8, 2025 at 09:41AM

Show HN: Life_link, an app to send emergency alerts from anywhere https://ift.tt/X5HI7Z9

Show HN: Life_link, an app to send emergency alerts from anywhere 2-factor authentication terrorizes me. Many years ago, I was at a friend's house and decided to quickly pop downstairs to buy something. When trying to re-enter the building, the main gate had locked. And since my phone, keys, and any spare cash were all left upstairs, I was stuck outside. Thankfully, Google, at the time, allowed users to send SMSes (SMSs?) through the Hangouts app, which I did after logging into my account from an internet cafe. (Back then people weren’t constantly connected to Facebook, etc.) Since that day I feared being locked out of my accounts by 2FA, simply because my phone (and my access codes) weren't with me. And while it's true that today people are always connected to messaging apps, I wouldn't be able to reach any of them without me being able to log into mine. That’s why I built life_link, an app that allows my loved ones to reach me, wherever they are, without having to care about 2FA or even needing to log in. To do so, they simply need to reach the app on a secret (short) URL. I've since expanded life_link by creating a "generator" app that can produce a pre-configured, single-file application, ready to be deployed on any static site hosting service and decided to open-source it for other people who might find it useful. You can find the life_link project and learn more about it here: https://ift.tt/IfmHo2V July 8, 2025 at 02:29AM

Show HN: Pelyos – A calm, minimal task manager for clarity and focus Hi HN! I’m the maker of Pelyos, a minimal task management app built to help individuals reduce daily stress and improve clarity. I built Pelyos after feeling overwhelmed by long, flat to-do lists that just kept growing. I wanted something timeline-based, simple, and more mindful — not a full-blown team tool or a cluttered app. I’d love your feedback on what’s working, what’s confusing, and what features would make this more useful for you. I’m currently bootstrapping this solo and hoping to make it truly helpful for knowledge workers, founders, and productivity nerds. Thanks for checking it out! https://pelyos.app/ July 7, 2025 at 12:52AM

Show HN: Simple wrapper for Chrome's built-in local LLM (Gemini Nano) https://ift.tt/oPix0Im

Show HN: Simple wrapper for Chrome's built-in local LLM (Gemini Nano) Chrome now includes a native on-device LLM (Gemini Nano) starting in version 138. I've been building with it since it was in origin trials, it's powerful but the official Prompt API is still a bit awkward: - Enforces sessions even for basic usage - Requires user-triggered downloads - Lacks type safety or structured error handling So I open-sourced a small TypeScript wrapper I originally built for other projects to smooth over the rough edges: github: https://ift.tt/LxwzqUh npm: https://ift.tt/NEtYBIr - Stateless prompt() method inspired by Anthropic's SDK - Built-in error handling and Result-based .Safe.* variants with neverthrow - Token usage checks - Simple initialization that provides a helper to trigger downloads (must be triggered by user action) It’s intentionally minimal for hacking and prototyping. If you need fine-grained control (e.g. streaming, memory control), use the native API directly: https://ift.tt/A0fFsD4 Would love to hear what people build with it or any feedback! https://ift.tt/LxwzqUh July 6, 2025 at 11:24PM

Show HN: Certimon – Free Telegram bot to monitor SSL certificate expiry https://ift.tt/8msArMg

Show HN: Certimon – Free Telegram bot to monitor SSL certificate expiry Hey folks, I'm a developer who got tired of having to rely on SaaS providers for such a simple task as monitoring an SSL certificate expiry. I had to create calendar entries just for the sake of making sure we don't forget it because of course warning emails got lost or the person responsible was on holiday.. So instead of "building yet another platform" I decide to take the un-sexy and simple route and put together a Telegram bot, called it Certimon. Thanks to Claude and Cursor I also put together a landing page for it https://certimon.com/ but I don't think you'll get any value out of it... If you want to give it a try, just add @CertimonBot to your Telegram or visit https://ift.tt/oDQBYSl to add directly. You can check a domain like this: /check google.com And get reminders like: /remind google.com 30 It's 100% free, supports as many domains as you need and you won't need to sign up to anything or download anything (assuming you already have Telegram). Hope someone other than me will find this useful, would love to hear your thoughts, comments and questions! Edit: Forgot to mention, but the operational cost of this solution is around £3 per month on AWS. -Tamas https://certimon.com/ July 6, 2025 at 03:29AM

Show HN: Distapp. Manage and distribute Android, iOS and Desktop app https://ift.tt/Dr9QG4X

Show HN: Distapp. Manage and distribute Android, iOS and Desktop app Hi HN, I built DistApp, a tool for managing and distributing Android, iOS, and Desktop app builds. I created it after App Center Distribution was discontinued, I wanted a way to easily share builds with the QA team and users with different groups. DistApp lets you manage multiple apps across different organizations and groups. It also supports self-hosting on your own infrastructure and is open-source https://ift.tt/bFR8peP You can try the free version by signing in with your Google account. I chose not to support email/password accounts to reduce abuse on the free version. But I’m open to suggestions if you think there’s a better way :) Thank you https://ift.tt/9VoiEvY July 5, 2025 at 11:54PM

Show HN: I Built a Pocket OS with JavaScript, Electron, and Gemini Welcome, traveler, to a new era of digital sovereignty. Oopis-OS has always been about crafting your own world. Now, with Pocket Oopis-OS 3.6, that world is no longer tethered to a single machine. This isn't just an update; it's a fundamental shift in architecture. We've transformed Oopis-OS into a single, self-reliant application that you can carry in your pocket. It asks for no installation, it leaves no trace, and it keeps your entire environment—your files, your settings, your history—right beside the application itself. The obstacle was dependency. The way is self-containment. https://ift.tt/13PV5OJ July 4, 2025 at 11:13PM

Show HN: Browse Netflix and Prime catalogs by country, with multilingual support I shared this a few weeks ago and wanted to post an update since it's improved quite a bit based on feedback: Titles and overviews are now translated into 18 languages You can browse full streaming catalogs by country and platform (e.g., Netflix UK, Prime Video Germany) Catalogs can be filtered by genre and country Per-season streaming availability is supported for TV shows The database now includes over 1 million movies and shows, with 1 million actor pages Coverage spans more than 130 countries No login required, fast load times The goal is to make global streaming availability searchable in a way that JustWatch and similar platforms don’t with per-country detail and full visibility in one click. Example: Netflix UK, filtered by crime genre: https://ift.tt/atfBJ0K...

Show HN: I rewrote my notepad calculator as a local-first app with CRDT syncing I launched NumPad v1 on here a few years ago, and back then it wasn't much more than a thin CodeMirror wrapper around the calculator engine I'd written. Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which should make it relatively easy to get document sharing working too. [1] https://automerge.org/ https://numpad.io June 30, 2025 at 01:40PM

Show HN: SteadyText: Deterministic LLMs: Same input → same output, every time https://ift.tt/X43mWaN

Show HN: SteadyText: Deterministic LLMs: Same input → same output, every time Hey HN! After spending way too many nights debugging flaky AI tests, I built SteadyText. It's a simple python library for deterministic llm generations and embeddings. We use it in production for: - Testing our AI features (zero flakes in 3 months) - CLI tools that need consistent outputs - Reproducible documentation examples It's not for creative tasks - this is specifically for when you need AI to be boring and predictable. Think of it as the opposite of ChatGPT. The coolest part? It includes a Postgres extension. You can now do: SELECT steadytext_generate('explain this query: ...'); And it will always return the same explanation. :) How it works: 1. Greedy decoding- Always pick the highest probability token (no randomness) 2. 8-bit quantization- Same numerics across all platforms It's easy to get started: uv tool install steadytext echo Hello | st https://ift.tt/ukaT1yH July 4, 2025 at 12:27AM

I was exploring how browser extensions can interact with and modify a page's state in real-time, specifically what kind of access was needed to intercept a process without breaking the UI. The test tool was a bit of fun on its own, so I polished it up and decided to post it here. https://ift.tt/Ri14HM0 July 3, 2025 at 11:20PM

Show HN: I created a privacy respecting ad blocker for apps https://ift.tt/GtaUJvZ

Show HN: I created a privacy respecting ad blocker for apps Hey HN, I’ve been working on developing my ad blocker for the last number of years and am proud to share that I have now released a new feature that blocks ads directly in apps — not just in a web browser. What makes this app ad blocker feature special? - All ad blocking is done directly on device, - Using a fast, efficient Swift-based architecture (based upon Swift-NIO) - Follows a strict ZERO data collection and logging policy - Blocks ads in all apps on iPhones, iPads and Macs It works as a local VPN proxy, so it filters all of your traffic locally without going through any third-party servers. The app ad blocker works across News apps, Social media, Games and even browsers like Chrome and Firefox. After using ad blocking in Safari for a long time, it is eye-opening how many ads and trackers are also embedded in apps themselves. The app is available via the App Store, with a 30 day free trial, before an annual subscription is required. I know there are many other ad blockers available, but I hope the combination of performance, efficiency and respect for privacy will mean that this particular feature is a valuable option. It also took a LOT of work to get this working seamlessly within the App Store and iOS / macOS limitations, so am glad the app has been able to finally be released into the world. Full details on the feature are in the release post: https://ift.tt/jMZ4EBa https://ift.tt/jMZ4EBa July 3, 2025 at 06:34AM

Show HN: Issue Duration Labeler – a GitHub Action that labels issue by age https://ift.tt/DtbkSXj

Show HN: Issue Duration Labeler – a GitHub Action that labels issue by age I’ve built *Issue Duration Labeler*, a GitHub Action that automatically adds *color-coded duration labels* to every issue in a repo: Default label thresholds: Green – ≤ 7 days (configurable) Orange – ≤ 30 days Red – > 30 days For open issues we compute “age” (creation → now). You can adjust the day thresholds and label colors in the workflow file, and choose whether labels update daily or only when they cross the next threshold. *Why?* I often lost track of how long tickets had been lingering, especially in older projects. A quick glance at the issue list or github project now tells us what’s fresh, what’s getting stale, and what’s officially ancient. It’s also handy for post-mortems: sort by red labels to see which bugs took the longest to close. *Link* https://ift.tt/sA3tUI1... https://ift.tt/mghLwuJ July 3, 2025 at 03:15AM

Show HN: Core – open source memory graph for LLMs – shareable, user owned https://ift.tt/cfEh4N2

Show HN: Core – open source memory graph for LLMs – shareable, user owned I keep running in the same problem of each AI app “remembers” me in its own silo. ChatGPT knows my project details, Cursor forgets them, Claude starts from zero… so I end up re-explaining myself dozens of times a day across these apps. The deeper problem 1. Not portable – context is vendor-locked; nothing travels across tools. 2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance. 3. Not yours – your AI memory is sensitive first-party data, yet you have no control over where it lives or how it’s queried. Demo video: https://youtu.be/iANZ32dnK60 Repo: https://ift.tt/3xcSd25 What we built - CORE (Context Oriented Relational Engine): An open source, shareable knowledge graph (your memory vault) that lets any LLM (ChatGPT, Cursor, Claude, SOL, etc.) share and query the same persistent context. - Temporal + relational: Every fact gets a full version history (who, when, why), and nothing is wiped out when you change it—just timestamped and retired. - Local-first or hosted: Run it offline in Docker, or use our hosted instance. You choose which memories sync and which stay private. Try it - Hosted free tier (HN launch): https://core.heysol.ai - Docs: https://ift.tt/0iqIXr5 https://ift.tt/3xcSd25 July 1, 2025 at 09:54PM
