jean

Jean is an open‑source development environment that lets you run AI agents in isolated git worktrees. You can run it on a laptop or on a dedicated Linux server and connect from a browser or the native desktop app. It supports Claude CLI, Codex CLI, OpenCode, Cursor, Pi, Command Code, Grok, and Kimi Code, and it is free forever under the Apache 2.0 license.

When you launch Jean you create a project that appears in the sidebar. Each issue, pull request, or prompt gets its own git worktree so the agent's changes do not interfere with others. The tool bundles a set of “magic” git commands that can commit, review, open pull requests, and resolve merge conflicts automatically. You can run several agents concurrently, each attached to a different branch or task. The desktop app can connect to multiple remote jean‑server instances, which keeps work running even if you shut down your local machine. A token‑protected browser UI is also available, and the team recommends using Tailscale or a similar VPN rather than exposing the server publicly.

Jean's opinionated design simplifies workflow selection. It installs the RTK proxy, which compresses tool‑output tokens by 60–90 %, and the Caveman Claude skill, which shortens Claude replies by 65–75 %. Each session has a dedicated terminal, chat history, and build of the source code tied to that worktree. The linear integration pulls issues from Linear directly into a session, and a linked‑projects feature shares context across related repositories. The interface is consistent whether you access it through the native app or the web UI; every session, terminal, and git action runs on the server that owns the project, eliminating the need to switch contexts.
