The open-source Grok Bot alternative: your own team of AI bots, in a chat app.
openmausbot.com · Download · Open source Grok Bot alternative, compared
OpenMausBot is an open-source Grok Bot alternative: an independent project inspired by Grok Bot, and the open-source alternative to Meta Muse, OpenAI dots and Cue by Manus — bring-your-own-agent, local-first, on the models you already have. Also known as MausBot; formerly OpenGrokBot. Not affiliated with xAI, Meta, OpenAI or Manus.
Every bot in the sidebar is a real agent — Claude or Codex running locally under the hood — with its own personality, its own model, its own cloud computer, and its own connected apps. Talk to them like contacts. Watch them work. Approve what matters.

One assistant in one box is the wrong shape for agents. OpenMausBot is an independent, open-source project inspired by Grok Bot — it keeps the idea (AI as a messaging app: a roster of bots you chat with, each with its own personality, memory of its thread, model, computer, and apps) and rebuilds it open, local-first, and on the agents you already have:
- Bring your own agents. Bots run on the
claude,codex, andgrokCLIs installed on your own machine — your existing logins and subscriptions, no new accounts, no proxy in the middle. Point any engine at a custom CLI binary (a versioned build or wrapper) in Settings → Engines. - Local first. One small harness server on
127.0.0.1owns every agent process. Transcripts, keys, and events live in~/.openmausbot, not a cloud. - Agents with hands. Each bot can use a cloud Linux desktop, an isolated Local VM, or—where the platform safety boundary is currently certified—your own computer, plus 500+ apps through Composio. Host control is available on macOS and Ubuntu Xorg after explicit opt-in. Ubuntu Wayland host control remains disabled while issue #345 is resolved.
Four closed personal-agent products shipped in seven weeks of 2026, and each one keeps the model, the computer and your data on its maker's side of the line. OpenMausBot is the open-source version of that shape: a team of agents in a chat app, each with its own model, its own computer and its own connected apps, running on your machine under Apache 2.0. If you searched for an open Muse, open dots, an open-source Grok Bot, an open Instinct or an open Cue, this is the repository.
| Looking for | What it is | How OpenMausBot differs | Read more |
|---|---|---|---|
| Open source Grok Bot | xAI's roster of bots on one shared cloud computer, Grok only, from a SuperGrok or Cursor plan | Same roster shape; any model per bot; your own machine; approval cards | Grok Bot vs OpenMausBot |
| Open Muse | Meta's single personal agent in a Meta cloud VM, US and Canada only | A team instead of one agent; runs anywhere; data in ~/.openmausbot |
Meta Muse alternative |
| Open dots | OpenAI's always-on agent inside ChatGPT, GPT only, Pro and Business Premium plans | Several agents; your Claude, ChatGPT or Grok login; no plan required | OpenAI dots alternative |
| Open Cue | Manus's invite-only agents with their own phone, email and wallet | No invite; OAuth instead of passwords; open source | Cue by Manus alternative |
| Open Instinct | Spear Street's invite-only agent that holds your passwords on a cloud computer | Ask for approval when you want it; signs in over OAuth; your machine | Instinct AI alternative |
All five side by side: Muse vs Grok Bot vs Dots vs Cue, and a decision guide in five questions: Which AI agent should I use?
|
A model picker with a provider rail — Claude and Codex models side by side, defaults marked, unavailable providers dimmed with the reason. Switch a bot's model mid-conversation. 
|
Open the Computer panel and the bot's cloud desktop spins up on its own — live screen preview while it works, "Open desktop" to take over in your browser, or point the bot at this Mac instead. 
|
|
Shell commands, file edits, and questions surface as inline cards — Allow / Deny / answer in chat. A permission broker turns every risky action into a decision you make, for cloud and local computers alike. 
|
A one-click marketplace over Composio Sessions: Gmail, Slack, GitHub, Notion, Linear and hundreds more. OAuth once, and every bot can use them as tools. 
|
|
Right-click any bot: pin, mark unread, edit profile, duplicate, copy conversation ID, hide, delete. It's a messaging app — your agents behave like contacts. 
|
Paste credentials in App Settings — they persist locally and the provider fleet hot-reloads instantly. Secrets are write-only: the UI only ever sees "configured" flags. 
|
Keep Work, Personal, and each project in separate channels without cloning your bots. Every channel has its own transcript, shared instructions, working folder, responder rules, and editable bot roster. File a channel and its bots under a named context, then rename it or change its members whenever the team changes.
Add a Cloudflare Workers AI token with its account ID, a TypeSafe Jev key, or an OpenRouter key and model, in Settings › AI › Routing and extraction and rooms set to Auto pick the bot that fits each un-mentioned message in a few hundred milliseconds, falling back to the room's lead whenever the decision model is off or unsure. See docs/decision-model.md.
Browse outcome-driven teams on BotMRR, then choose Add to OpenMausBot. The app
opens a review screen before creating the bots, Chief of Staff, channels, playbooks, connector checklist,
and suggested routines. You can also import the same .md file from disk or paste its public GitHub URL
in Teams → Import.
The format stays portable: OpenMausBot reads the structured YAML frontmatter for a reliable one-click install, while Grok, Claude, ChatGPT, and people can follow the ordinary Markdown playbook. Connections remain off until you approve them, routines arrive paused, and packages never carry credentials, conversations, permissions, memory, or computer access. Browse the open-source playbook repository or read its portable format.
Right-click a department and choose Share department… (or use Templates → Share) to save the whole department as one file: its bots with their instructions, pictures and skills, group chats, routines, shared instructions, Chief of Staff, connection slots and each bot's starter notes (untick them to leave them out). The dialog shows exactly what the file holds before you save it. Chat history, keys and passwords, model choices and computers never go in, and anything that looks like a secret is removed from the text. Whoever imports it gets new bots on Ask, skills switched off and routines paused. See docs/team-sharing.md. Desktops connected to an organization also get Templates → From {Organization}: the packages its Admin shares, added with one click, skills switched on. See docs/org-library.md. Your New bot defaults can travel too, as a preset bot that appears in New bot (in a team file, or on their own with Share as preset…). See docs/presets.md.
Press the speaker on any reply, or switch a bot to read its answers out as they land — so you can listen to what ran overnight while you make breakfast. Hit call and it's a conversation: it hears you, tells you what it's doing while it works, and asks for approvals out loud.
Choose ElevenLabs, Fish Audio, Grok (xAI), built-in Mac voices, or a local Chatterbox server in an agent profile. Paste a cloud key once when needed, pick a voice, and every bot can talk. Give a bot its own voice and a channel stops sounding like one person.
For Grok, save your xAI API key in Settings → Connections, then choose Grok (xAI) and a voice under the bot’s Voice & alerts. It reuses that host-side key and returns MP3 audio for spoken replies and calls. Language is detected automatically from the reply text; quality varies outside xAI’s officially supported languages. This adds speech synthesis to the existing call flow; microphone transcription remains unchanged.
Also in the box: streaming replies with tool-run activity chips · dictation from the composer mic (on-device Apple speech recognition on macOS, Fish Audio speech-to-text on Windows and Linux, in the desktop app) · SupaMaus cursor mascots with role-aware expressions · screenshots of the bot's work folded into the transcript.

Two processes. The app holds no transports of its own — it sends typed commands over HTTP and folds one SSE event stream into state. The harness server owns every agent process and normalizes each provider's native protocol into one canonical runtime event stream (logged per-thread as NDJSON).

| Layer | Where | What it does |
|---|---|---|
| Drivers | server/drivers/ |
One per provider: Claude, Codex, and Grok Build over their local CLIs (stream-JSON / JSON-RPC / ACP), plus a cloud-computer agent. Unknown drivers degrade to "unavailable", never crash the fleet. |
| Harness | server/harness/ |
Registry (configs → live instances) and the fan-in event bus every client folds. |
| API | server/index.ts |
Bots, turns, approvals, model catalog, computer lifecycle, connectors, config — HTTP + SSE. |
| Voice | server/tts/ |
ElevenLabs, Fish Audio, Grok (xAI), built-in Mac voices, or local Chatterbox. Cloud keys stay on the harness; markdown is rewritten into something worth hearing before it is spoken. |
| App | src/ |
The chat shell. Server-backed store, one reducer, zero client-side transports. |
| Desktop | electron/ |
macOS, Windows, and Ubuntu shells with an embedded harness and platform capabilities; Apple speech stays macOS-only, Ubuntu Xorg has opt-in local control, and Wayland remains fail-closed. |
OpenMausBot ships a stdio MCP server for external clients such as Claude Desktop and Cursor. It exposes a deliberately bounded team control plane: inspect bots and channels, read/search compact transcript pages, create and configure bots/channels/tasks, send work, wait for completion, switch models, and interrupt turns. It does not expose approval grants, deletion, arbitrary settings, credentials, or computer lifecycle.
See MCP server setup and tool reference.
The openmausbot command drives a running workspace without a screen: set a
team up from a file, give a bot one job, wait until it and every teammate it
asked are done, and export what they made. One JSON document with --json,
and exit codes a script can branch on.
openmausbot team apply team.yaml
openmausbot run "Room Lead" "Rehearse the launch of https://example.com" --export ./outSee Run OpenMausBot from scripts and CI.
Released builds (latest release): the harness server is embedded, so no separate server setup is required.
