Official site

Jean review

Jean gives every task, issue or pull request its own git worktree, then runs several coding agent CLIs against them in parallel. It is a desktop app plus a headless Linux server, Apache 2.0 licensed and free. Our source is the vendor's site and GitHub pages, read in November 2026. We never ran it.

The site names eight backends, including Claude, Codex, OpenCode and Cursor. The README says ten. Jean reads MCP servers from the CLIs you have installed.

Servers and remote use

You can run `jean-server` on Linux, or let the desktop app install it over SSH. Projects from each server share one sidebar. Any running instance can serve its UI to a browser, including a phone, behind a token. We found no iOS or Android app.

Release and cost

Release v1.0.14 came out on 6 November 2026, and the repository showed 1,399 stars on 7 November 2026. The site says there are no paid tiers or usage limits; you bring your own agent subscriptions. The licence file is Apache 2.0.

Rough edges

It suits developers who want a free, self-hostable workspace for agent CLIs in separate worktrees. Comparable worktree-based workspaces are Conductor, a Mac app, and Orca, which has mobile companion apps.

Facts: platforms, price and licence

platforms
macOSWindowsLinuxWebRelease assets include a universal macOS dmg, Windows exe/msi, and Linux AppImage/deb/rpm (x86_64 and arm64). The site says the desktop app is tested on macOS and that Windows and Linux testers are needed; the README says Windows is not fully tested and Linux is community tested. The headless jean-server targets Linux amd64/arm64 only. Web access serves the UI in a browser from a running Jean instance.
