What's different · Install · Imitation learning · Architecture · Demo · How I built it
Watch Claude navigate Tinder, Reddit, and Robinhood — sites the official extension can't reach.
The official [Claude in Chrome](https://code.claude.com/docs/en/chrome) extension gives Claude Code full browser automation — as long as you stay within Anthropic's allowlist of "safe" sites. Open Claude in Chrome is a clean-room reimplementation that strips the restrictions while keeping all 21 MCP tools and matching the official extension's performance.
