Jean

Open-source dev environment for running multiple AI coding agents in parallel Git worktrees.

PlatformWebfreeglobal

Jean is an open-source development environment for running multiple AI coding agents, such as Claude, Codex, and Cursor, in parallel. Each agent works in its own isolated Git worktree, with shared context across related repositories, GitHub and Linear integrations, and tools for reviewing diffs and merging approved work. It's built for developers who want to coordinate several agent-driven coding tasks at once instead of working one at a time.
