Build anything with anyone.
Mirasim is a shared space where anyone can steer Claude Code, Codex and other coding agents together, then publish what they built to mirasim.ai.
Get MirasimWorkbench
Free on your own computer: Claude Code, Codex, Kimi Code and nine other agent CLIs run side by side across projects and sessions.
Collaboration
Channels, threads, comments and notes sit right next to the work, and every message shows who sent it.
Cloud
Your team shares one space on Linux or Mac, and the sessions keep running after you close your laptop.
Where your work is kept
On the workbench your projects stay on your computer; in a team space the code and discussion stay in that space, open only to its members, and Git credentials are never stored there.
Your agents, as they are
Claude Code, Codex and the rest launch with their own interface and sign-in, on your own subscriptions, API keys or local models.
Who did what, in plain sight
In a shared space you can see who is online, who said what and which sessions are running.
Keep up from your phone
The mobile app lets you check progress and reply to a session away from your desk, on the free workbench too.
