iPhone & Apple Watch
The iOS companion carries the whole product in your pocket: the roster, full chats, approval cards, task switching, live computer frames — and an Apple Watch app for approvals on the wrist, so a bot that stops and asks never waits for you to reach a desk.
Distribution: the iPhone and Watch build is not on TestFlight yet. The TestFlight join link appears here the moment a build actually clears App Store Connect processing and a test group is open — until then there is nothing to click, and a link here would be a dead end.
In the meantime, the same chat, approvals and tasks work in the browser on any phone: open muster.today/app and add it to your home screen.
Muster CLI
No installer at all — the CLI is a single file with zero dependencies (~51 KB, Node 22+). It connects to an existing Muster workspace so you can check tasks and answer approvals from a terminal. The desktop app handles local setup.
curl -fsSL https://muster.today/downloads/muster-cli.mjs -o muster && chmod +x muster && ./muster help
For installation and setup, read the installation guide.

We host Muster at muster.today. You do not need to deploy a server or manage a container. Use the desktop app when a task needs tools on your computer.
