About Jean
Jean is a dev environment for AI agents used by developers and ML teams. It runs AI agents in parallel in isolated workspaces on your laptop or a dedicated server, and you can connect from a browser or the native app; it’s open source and free forever.
Key Features
In practice, Jean centralizes context, runs parallel agents, and lets you work across repos from one workspace:
Linked Projects
Make multiple repos feel like one knowledge base by linking app, docs, backend, and libraries so agents see surrounding context.
Isolated Workspaces
Each agent runs in its own isolated workspace, preserving state and avoiding cross-task bleed.
Magic Git Commands
A built-in commands palette handles common git tasks without leaving the workspace—quick commits, merges, and reviews.
Server/Web/Native access
Access the same workspace from desktop, browser, or mobile; run jean-server on a Linux host and connect via token-protected HTTP/WebSocket port 3456, with tailscale recommended.
Summary
Best for AI-focused development teams, platform teams coordinating multiple repos, and product teams prototyping AI agent workflows.
