Description
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.

Could you build this?
Yes This is an in-browser AI agent running client-side using browser APIs (Web Workers, IndexedDB, Web Storage) to execute tasks, completely vibe-codeable with modern LLM web frameworks.

Competitors mentioned: GNU/Linux (naming comparison)
Concerns raised: Product name too long, unlikely adoption, Security claims overstated for proof of concept, Encryption without passphrase doesn't protect against indexed DB access, Claude can POST to any URL without user confirmation, Inconsistent security: Telegram token stored plaintext vs AES256 for Anthropic
Feature requests: Confirmation step for outgoing requests, Sandboxing for JavaScript tool (iframe with null origin), Clearer README about proof of concept status, Persistent background task execution
