OpenMausBot
An open-source, local-first messaging app that lets you run and chat with multiple AI agents as contacts, each backed by a different model, with access to 500+ app integrations and cloud desktops.

Description
Managing several AI assistants usually means several browser tabs, each with its own login and context. OpenMausBot treats AI agents like contacts in a messaging app instead — you message "Claude" or "Codex" the way you'd message a coworker, and each one keeps its own personality and model.
Built as an open-source alternative to Grok's Bot feature, OpenMausBot is local-first: all conversation transcripts are stored on your own machine (in ~/.openmausbot) with no cloud proxy required. Each contact can run a different model (Claude, Codex, or Grok), and agents can act on 500+ app integrations via Composio, work inside cloud desktop environments with live screen preview, or reach into your local machine with a permission-based approval system for risky actions. It supports macOS, Windows, Ubuntu, iOS, and Android, and includes text-to-speech via ElevenLabs.
💬 Our review
The short version: OpenMausBot's core idea — treat AI agents as messaging contacts you can run in parallel, each with its own model — is a genuinely different UX from the single-chat-window pattern most tools use, and going local-first for privacy is a meaningful differentiator.
As an explicit open-source alternative to Grok's Bot feature, the comparison is direct: Grok Bot is polished and backed by xAI's infrastructure, while OpenMausBot trades that platform integration for full data ownership and the freedom to mix models from different providers in one interface. The 500+ integrations via Composio and cloud-desktop access give it real practical reach beyond a chat toy. Launched just this month (August 2026), it's described by its own developers as "early but real," so expect some instability; a good pick for privacy-conscious developers who want multi-model orchestration without a single vendor's chat app, less so for users wanting a mature, support-backed product today.
