About OpenBUA

OpenBUA is a browser-use agent that works inside your everyday Chrome, with your existing logins for Gmail, LinkedIn, GitHub, Notion and CRMs, so it can research across sites, fill long forms and send outreach without cloud browsers or cookie exports; it alerts you when a CAPTCHA needs solving. You connect your own Gemini API key and pick a model on its free tier, and can optionally connect another supported provider with your own key. Task context goes only to your AI provider. An MCP bridge also lets agents such as Claude Code, Codex or Cursor drive your browser. The extension is free and open source.
