I was wondering... why do we need a Mac Mini, a VPS, or a Docker container to run OpenClaw?Your browser already has a secure sandboxed OS, a database, a filesystem, and a JS engine. What if we just... used those?So I built OpenBrowserClaw inspired by the simplicity of NanoClaw but running entirely in a browser tab.- Claude API with full tool-use loop- Shell commands in a v86-emulated Alpine Linux (yes, a Linux VM in WASM, in your browser)- File I/O via OPFS- Data persistence in the browser local storage- Telegram integration over plain HTTPS- Zero runtime dependenciesNo server. No deploy. No infra. Open a tab, paste your Claude API key, start chatting.It even works as a PWA, install it on your phone if you want.The whole thing is MIT-licensed and open source: https://github.com/sachaa/openbrowserclawOr just try it right now without cloning anything: https://www.openbrowserclaw.com/Sometimes the best server is the one you already have open.
