ego (lite) is a free, MIT-licensed browser where external AI agents run web automation in isolated spaces.
ego (lite), developed by Citro Labs, is a macOS browser that serves as both a daily browser and a runtime for external AI agents such as Claude Code, Codex, and Cursor.
Agents work in isolated "Spaces" that inherit the user's Chrome login state, and browser actions are exposed to agents as JavaScript functions through the open-source ego-browser skill rather than step-by-step CLI calls. One-click Chrome migration transfers tabs, bookmarks, passwords, extensions, and cookies. The company reports internal benchmarks of up to 3.45x faster than browser-use and Vercel's agent-browser on fewer tokens; the ego-browser harness is MIT open source while the browser binary is closed source.
