Show HN: Rouler – Steer Windows traffic per app or IP across multiple interfaces https://ift.tt/VmgxjwM
Show HN: Rouler – Steer Windows traffic per app or IP across multiple interfaces Hi HN, Rouler is "rules for your routes". It allows you to steer network traffic across multiple network interfaces on Windows. For example: - Run Tailscale, Mullvad and OpenVPN official clients simultaneously. - Use Rouler to send Slack via the OpenVPN connection, Chrome + an IP range via Tailscale and a torrent client via Mullvad. Rouler is VPN agnostic, so you can "split-tunnel" with anything that sets up a windows network interface. I'm an independent developer from Australia and have been working on Rouler for a bit over a year. It's been a challenging project to say the least, but I'm really happy with how it's turning out. I have spent a great deal of time building and throwing things away, starting over, belting the initial poc into something that I find intuitive... hopefully others do too! I've done all the testing, fixing and improving I can, so now it's open for public beta. I'd love to hear your feedback... and there are some specific points I'm interested in hearing about listed on the Rouler website. Please reply with any questions you might have. Thanks for reading! Brendan p.s. Rouler is "built in Rust" TM ;-) --- On AI (skip if you're sick of hearing about it): Since AI is the hot topic and people are naturally cautious about it, I'll add some quick notes about it, specifically about the driver development as that's the key thing to get right. The driver is hand written and every detail has been poured over many times over. I spent somewhere around 6-9 months manually building and testing just the driver, staring at Dbgview logs, wireshark logs, windows route tables, restarting VM's back to their snapshot and manually copying things across to start again. That's not always the most efficient way of doing things, but it's the way it had to be done. If I had tried to vibe code it Rouler simply wouldn't exist. I did try to lean on AI at times, but it constantly sent me in the wrong direction, told me things weren't possible, tried to take shortcuts and implement poor performing trade-offs. It also loved to hallucinate the windows api. Keep in mind this was around the Opus 4.1 - 4.6 days. Outside of the driver, in user mode land, AI has crept more and more into my workflow. I've had a lot of success utilising the latest models in the app in particular, and I purposefully separated the UI and core logic so I'm able to quickly iterate on the UI. I've also found AI very useful for scripting and refactoring. It has built some great scripts that would've taken me days or weeks to build and fine tune. https://rouler.io/ October 20, 2026 at 09:21AM

Show HN: Maali – Privacy-first personal finance app with a local AI analyst https://ift.tt/7p8sR5q
Show HN: Maali – Privacy-first personal finance app with a local AI analyst I never felt comfortable signing up for cloud budgeting apps and having them store all of my financial data on their servers. I also didn't find locally hosted options that I liked using. That led me to build Maali ( https://maali.app ) over the past year. It is currently a Mac and Windows app that lets you track spending, budgets, recurring bills, income, net worth, and more. It stores all of your data on your computer. You can bring your data in by either manually importing bank statement files (CSV/PDF), or by using SimpleFIN, a third-party bridge that you set up once and it keeps your data in sync. Since SimpleFIN introduces a third party that moves your data, I also added a power-user feature where Maali watches a folder (per account) and imports files dropped there, so you can automate downloads however you like and keep everything local. It also has an optional AI analyst (local Gemma 4 E4B model) that provides commentary on your spending and flags anything unusual about your finances. I realize that mobile is a big part of convenience for people. Maali lets you set up a phone web app over your own Tailscale network, paired by QR code. I'm also close to launching iOS/Android mobile apps that keep data in sync between the desktop/mobile apps using end-to-end encryption. My goal is to provide a great user experience with maximum convenience without sacrificing privacy. The full app is free to use for 30 days (no card/signup needed). After that, if you find it useful and want to continue using it, it's $99 one-time. There's a live demo on the site ( https://maali.app/today ) with synthetic data so you can get a feel for it. Would love to hear any feedback that you have. https://maali.app/ October 20, 2026 at 12:55AM

Show HN: WhatsApp MCP running free on Cloudflare https://ift.tt/nGlHcUS
Show HN: WhatsApp MCP running free on Cloudflare I wanted my humble Claude on mobile to access my WhatsApp messages but the only options I could find either required WhatsApp Business or an actual server to run Baileys on. I wanted to run it for free on ClaudeFlare and with my personal WhatsApp account, so I built this. Important feature - it connects to your Google account as well as WhatsApp to grab the names of all your WhatsApp contacts, otherwise you get only phone numbers for many of them and search doesn't work properly. This is a single user install because it's both gray area and very private - so point your agent at the repo and let it set things up. https://ift.tt/zHXvJ5x October 19, 2026 at 03:06AM
