Mirasim for desktop and phone
Mirasim runs native on macOS, Windows and Linux, and the phone build comes with you, so you can pick up on whichever screen you are at.
No invite code needed. Sign in with GitHub, Google or email and you're in. Everything that runs on your own model accounts works from the first launch; a plan or code only matters for usage on Mirasim's quota.

What's inside
Your agents, side by side
Claude Code, Codex and 10 other agent CLIs, several sessions at once, on your own subscriptions and API keys. Switch agents mid-session and the conversation comes with it.
Keep up from your phone
The mobile app and 8 IM channels, QQ among them, show progress and let you reply to a session when you're away from your desk.
Work together in a team space
A team space runs Linux or Mac and is shared by up to 25 people. Channels, threads and comments sit next to the sessions, and the work keeps running after you close your laptop.
The iPhone build ships through TestFlight, Apple's beta channel, not the App Store. Install TestFlight first, then open the invite above to join. Its version number moves on its own schedule and may differ from the desktop app.
The macOS app is signed and notarized. Mirasim keeps itself up to date after install; verify any download against its SHA256SUMS.
