What is it?

Jean is a workspace for AI coding agents. It runs Claude, Codex, Cursor, OpenCode, Pi, Command Code, Grok, Kimi Code, Antigravity and Muse in parallel, and gives every task its own git worktree so changes stay isolated. Git operations, diff review, a built-in terminal, and GitHub, Linear and Sentry integrations are combined in one interface.

Jean ships as a native desktop app and as a headless `jean-server` for Linux. The desktop app can show local and remote projects in one sidebar, with each action running on the server that owns the project. The web UI is served over HTTP and WebSocket with token authentication, so it can be opened from a browser or phone.

Jean uses your existing CLI installations and subscriptions, and runs on machines you control.
