Show HN: Boop – tiny, self-hosted push notifications for your apps built in Go https://ift.tt/q0x1MRC
Show HN: Boop – tiny, self-hosted push notifications for your apps built in Go Hi HN, I built Boop because I wanted application events sent directly to my phone without paying for another service or routing everything through Slack or Telegram. Boop is a small, open-source server paired with an open-source iOS app. The server currently uses around 8 MB of memory on my machine. It’s deliberately not an observability platform or a replacement for Sentry. It receives events from your applications, sends native push notifications, and keeps them in a purpose-built mobile inbox. I use Elixir, so I built an integration for ErrorTracker. ErrorTracker still captures and stores the errors; the plugin sends them to Boop so I can see them on my phone: https://ift.tt/U3vQADE There’s also a general Elixir client: https://ift.tt/FKucrnU And a Node client: https://ift.tt/V4xg3kv The iOS app can be built and installed locally. I’ve included instructions for configuring private push notifications for your own device, so you don’t need to release anything through the App Store. Although errors were my original use case, Boop can receive any event worth knowing about: failed jobs, deployments, signups, payments, low disk space, or anything else your application can send. Built in Go because I wanted to save memory on my self-hosted machine so Go and Svelte felt like a good combo. Everything is free and open source. It’s early, so I’d especially appreciate feedback on the architecture, setup process, and which integrations would make it useful to others. https://ift.tt/CHVhEZ0 August 29, 2026 at 12:33AM

Show HN: Voronoi Go https://ift.tt/beTJwj4
Show HN: Voronoi Go I posted once before but wanted to share again because a lot has changed. There's now a fairly strong bot to play against (contributed by a community member) and also correspondence games. The combination of these things helps a bit in finding people to play against. https://voronoigo.com/ August 27, 2026 at 11:33PM
Show HN: Music Visualizer|New MilkDrop engine and various types of reactive art https://ift.tt/6hIyDSi
Show HN: Music Visualizer|New MilkDrop engine and various types of reactive art This is my take on what a modern music visualizer looks like. Five engines, one HDR pipe, with 12 pass post chain. (LUT, God Rays, Bloom) Images, video, .milk, glsl, webgpu, three.js,, and more. Span, Mirror, Wallpaper, Logos, OBS, Spout (in/out), Ableton, NDI, capture, games, workshop... It's pretty, it's different, and was built by one person with dog by side. It's free with DLC's, be one of the first to try it. The audio path is the most innovative part, and you won't even know it's there. https://ikandy.app/ August 27, 2026 at 11:33PM

Show HN: Convolens – Real time slides and fact-checking https://ift.tt/wnWZEJu
Show HN: Convolens – Real time slides and fact-checking Convolens is a Mac desktop app that records and transcribes your conversation on device, and turns it into slides, fact-checks, and infographics. I built the real time slides because I'm constantly losing focus during meetings and needed something I can quickly glance at and know exactly where I'm at and what happened during my "snooze". As a whole, Convolens lets you: - Record and transcribe your meetings / sessions locally. - Generate Slide decks, Infographics, and Fact-checks from your conversation (among other things). - Chat with your meeting/session and research anything that you need. Anyway, please check out the app we have a great free tier. Any and all comments are greatly appreciated! https://ift.tt/70u4jlO August 27, 2026 at 01:20AM

Show HN: LatticeDB – Like SQLite but for graph databases We have been using graph DBs more and more at work. I found them painful to work with locally and decided to try and build something better. https://ift.tt/kg2p1Lw August 25, 2026 at 10:22PM
