Citrolabs open-sourced ego-lite, and it picked up close to 1,000 GitHub stars in a single day. It’s a Chromium browser built so you and your AI coding agents can drive the same window in parallel — not a CLI, not a headless sandbox, an actual browser.
One browser, your real logins
The core idea: every agent gets its own isolated Space, but they inherit your actual Chrome session — cookies, extensions, bookmarks, logged-in accounts. The agent never re-authenticates into some throwaway automation browser; it just uses the sites you’re already signed into. You browse up front, agents work in the background, nobody steps on anybody’s tabs.
How agents actually drive it
Instead of shell commands, agents control pages by writing in-page JavaScript — snapshot, fill, click, navigate — exposed through the open-source ego-browser skill. It plugs straight into Claude Code, Codex, and Cursor. Citrolabs claims 2.5x faster than Vercel’s agent-browser on hard tasks with fewer tokens, and its Skill caches winning workflows so repeat runs go up to 5x quicker.
