    BrowserOS – "Claude Cowork" in the browser▲88

    Hey HN! We're Nithin and Nikhil, twin brothers building BrowserOS (YC S24). We're an open-source, privacy-first alternative to the AI browsers from big labs. The big differentiator: on BrowserOS you can use local LLMs or BYOK and run the agent entirely on the client side, so your company/sensitive data stays on your machine!

    MyNixOS – Create and share Nix and NixOS configurations▲200

    Hello HN! I want to show you MyNixOS.com - a website I've been working on this year to make it easy to create and share Nix and NixOS configurations.
