Download OpenMausBot

Free and open source, for macOS, Windows, and Ubuntu, with Android and iOS apps to carry your bots around. The harness is embedded, so there is nothing else to install — download it, paste the keys you already have, and meet your first bot.

Once it opens

Bring a key, or a CLI you already have

Bots run on the claude, codex, and grok CLIs installed on your machine, using your existing logins — or on API keys you paste into settings. Any one of them is enough to start.

Nothing else to install

The harness server is embedded in the app. There is no separate daemon, no Docker, and no account to create.

Everything stays on your disk

Transcripts, keys, and events live in ~/.openmausbot. Local-first is the default, not a setting.
