Jean is an opinionated native desktop app built with Tauri that gives you a powerful interface for working with Claude CLI, Codex CLI, Cursor CLI, OpenCode, PI, Command Code, Grok, and Kimi Code across multiple projects. It has strong opinions about how AI-assisted development should work - managing git worktrees, chat sessions, terminals, GitHub and Linear integrations in one cohesive workflow.
No vendor lock-in. Everything runs locally on your machine with your own CLI installations.

Every Jean instance can run Web Access: an embedded HTTP + WebSocket server that serves the same UI in a browser. That applies to both:
| Mode | How you get Web Access |
|---|---|
| Native desktop (macOS / Windows / Linux) | Settings → Web Access - enable the HTTP server, set port/bind address, copy the token URL |
Headless server (jean-server) |
Always on - the process is the Web Access endpoint |
Use it to open Jean from another machine on your LAN, a phone/tablet browser, or a remote host. Token authentication is on by default; keep it enabled for any non-localhost bind.
Web Access binds a normal TCP port (default 3456). For access beyond the local machine, prefer a private mesh VPN rather than exposing the port to the public internet:
jean-server --host 127.0.0.1 plus tailscale serve --bg 3456 so the
browser gets real HTTPS (clipboard and other secure-context APIs work).
Binding the Tailscale IP directly (--host tailscale) is HTTP-only and
browsers will treat it as an insecure origin.127.0.0.1Keep token auth enabled, use a long random token
(openssl rand -base64 32), and avoid binding 0.0.0.0 on untrusted networks
unless you also terminate TLS and restrict who can reach the port.
127.0.0.1 for local only, LAN IP,
0.0.0.0, or your Tailscale IP)?token=...) in a browser, or share it with
devices that can reach that hostThe native app can also connect to a remote Jean Web Access server (title bar server icon → Add remote) while keeping the desktop shell.
jean-server)Run Jean as a standalone Linux server with browser Web Access - no desktop window, GTK, or WebView required. Linux amd64 and arm64 only (glibc + OpenSSL 3; Ubuntu 22.04+ / Debian 12+ recommended).
Interactive install (prompts for bind interface + port when a TTY is available):
curl -fsSL https://raw.githubusercontent.com/coollabsio/jean/main/scripts/install-jean-server.sh | sudo bash
Non-interactive (defaults to 127.0.0.1:3456, or pass --host / --port):
curl -fsSL https://raw.githubusercontent.com/coollabsio/jean/main/scripts/install-jean-server.sh | sudo bash -s -- -y
Or from a clone:
sudo ./scripts/install-jean-server.sh --host 127.0.0.1 --port 3456 -y
The installer downloads the latest release, installs the binary, writes an env
file (host/port/token), and registers a systemd service. Re-run to upgrade;
existing tokens are preserved unless you pass --token.
Common options:
# Public bind with an explicit token
sudo ./scripts/install-jean-server.sh \
--host 0.0.0.0 \
--port 3456 \
--token "$(openssl rand -base64 32)" \
-y
# Tailscale-only bind (auto-detect Tailscale IPv4) - recommended for remote use
sudo ./scripts/install-jean-server.sh --host tailscale -y
# Current user only (user systemd unit)
./scripts/install-jean-server.sh --user-install --host 127.0.0.1 -y
jean-server --host 127.0.0.1 --port 3456
# or with an explicit token:
jean-server --host 127.0.0.1 --port 3456 --token "$JEAN_TOKEN"
--host accepts localhost, presets (tailscale, lan, 0.0.0.0, …), or
any IP/hostname to bind only that interface. Docker images are also published
as ghcr.io/coollabsio/jean-server.
See docs/headless-server.md for systemd details, reverse proxies, updates, native remote connections (including Install via SSH from user + IP), and security notes.
