Mirasim for desktop and phone

The full build space runs native on your Mac, and the phone build comes with you — same release, same loop, whichever screen you are at.

What's inside

Every agent, curated

Claude Code, Codex, and Mirasim's native agent — up to six panes, each in its own git worktree.

Bring your own stack

Your subscriptions and API keys. Swap models mid-build, add MCP servers, run local models.

The eval loop, built in

Send any build to simulated users; the evidence comes back as your next tasks.

Coming soon

iOS. The build already ships to TestFlight; the public invite is not open yet. The moment it is, it appears in the button above — nothing else here changes.

Signed build. Mirasim keeps itself up to date after install; verify any download against its SHA256SUMS.
