OpenMausBot (MausBot)

OpenMausBot is an open-source, local-first app for running your own team of AI agents. Every bot in the sidebar is a real agent (Claude Code, Codex, Gemini CLI or a local model, running on your own machine) with its own personality, model, memory of its thread, computer and connected apps. You talk to bots like contacts, watch them work, and approve the actions that matter.

It is the open alternative to closed, cloud-only agent chat products: bring your own agents and subscriptions, no proxy in the middle, and all transcripts, keys and events stay in ~/.openmausbot on your machine. One local harness server owns every agent process. Agents can work in an isolated local VM, a cloud Linux desktop, or, after explicit opt-in, the host computer, and reach hundreds of apps through MCP and built-in integrations.

OpenMausBot ships as signed and notarized desktop builds for macOS (Apple silicon and Intel), Windows and Linux, with companion iOS and Android apps on the App Store and Google Play. Since its first release in August 2026 the project has passed 5,400 GitHub stars and 900 forks, with 80 tagged GitHub releases (the desktop app is at v0.1.122) and contributions from more than 140 people. It is written in TypeScript (React 19, Electron, Swift and Kotlin for the phone apps) and licensed under Apache-2.0.
