MausBot (OpenMausBot)

MausBot, formally OpenMausBot (formerly OpenGrokBot), is a free, open-source desktop app for running a team of AI bots from a chat-style interface. Each bot is a real agent, such as Claude or Codex running locally, with its own job, model, working folder, computer and connected apps. The site and README pitch it as “the open source Grok Bot alternative”; the README says it is an independent project inspired by Grok Bot and not affiliated with xAI, Meta, OpenAI or Manus.

What it gives you

  • A roster of bots, like contacts. Create bots, pin, duplicate, hide or delete them. Each has its own personality, model, thread memory, computer and apps.
  • Bring your own agents. Bots run on the agent CLIs installed on your machine, using your existing logins and subscriptions with no proxy. The site lists engines including Claude, Codex, Grok, Cursor, Kimi, Droid, Antigravity, OpenCode, Qwen, Hermes and Pi; the README names claude, codex and grok first and lets you point an engine at a custom CLI binary.
  • Local-first. A small harness server on 127.0.0.1 owns the agent processes. Transcripts, keys and events live in ~/.openmausbot. Prompts and context still go to whichever model provider you choose.
  • Agents with hands. A bot can use a browser, terminal and files, a cloud Linux desktop with live screen preview, an isolated local VM or, after explicit opt-in on macOS and Ubuntu Xorg, your own computer. Computer control is through Cua and cloud computers through boat.dev (README and site).
  • 500+ apps through Composio. Examples named on the site: Gmail, Slack, GitHub, Notion, Linear, HubSpot, Stripe, Google Calendar and Sheets.
  • Automations. Defined in plain language, on a schedule or calendar, by webhook or on app events.
  • Approvals. Supported actions can ask for confirmation in chat before they run. The site says coverage depends on the engine and tool.
  • Voice and phone. Live voice calls use your own OpenAI key; iOS and Android companion apps connect to your bot host. The desktop app ships in 10 languages.
  • MausBox. A planned hardware box for running MausBot and open models at home; only a waitlist exists.

Billing model

The desktop app is free with unlimited bots, but it only works while your computer is awake and online. Optional Cloud plans (Starter, Pro, Max) add an always-on cloud machine, with larger machine size, storage, monthly computer-hours, voice allowance and number of concurrent bots at each step up. Team, Business and Business self-hosted tiers add shared machines and an admin console, and Business starts with a sales call. Plans are monthly with no contract. AI usage is never included: you pay your model provider through your own Claude or ChatGPT account or API key, apart from a small monthly Claude credit on Pro and Max. See https://mausbot.com/pricing for amounts.

Key differentiator

An open-source, bring-your-own-agent take on the “AI as a messaging app” idea: it reuses CLIs and subscriptions you already have, keeps data on your machine, and adds a paid cloud computer only when you want bots running with the laptop closed. Source: README and site, which are the project’s own claims.

Pick something else when

  • You want the original closed product: Grok Bot.
  • You need a vetted, supported enterprise product: the project is only a few months old and ships a release almost every day, so expect churn.

Open items

  • Release cadence is very fast (v0.1.x); features such as host control have platform caveats in the README (for example Ubuntu Wayland host control is disabled pending an open issue).
  • Approval coverage differs by engine and tool, per the site; how reliable the approval gates are was not tested.
  • Security of host control and of the Composio-connected apps was not reviewed.
  • The README warns that no cryptocurrency token is associated with the project, and that any coin using the OpenMausBot, Maus or SupaMaus name is unaffiliated.
  • Funding, company structure and the “partners” listed on the site (startup programs, boat.dev) were not researched. boat.dev is named as the powering sponsor.
