OpenMausBot

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, and grok CLIs 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 127.0.0.1 owns 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.

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?

🧠 Pick a brain per bot 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.	🖥️ Every bot gets a computer 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.
🙋 Bots ask before they act 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.	🔌 Connected apps 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.
🗂 Manage bots like chats 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.	🔑 Keys once, everything lights up 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 TypeSafe Jev key in Settings → Decision model 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 Jev 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 team and choose Share team… (or use Templates → Share) to save the whole team 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 · native macOS dictation from the composer mic (on-device Apple speech recognition — 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).

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.

Released builds (latest release): the harness server is embedded, so no separate server setup is required.

See the Ubuntu Desktop guide for installation, capabilities, and troubleshooting. Any desktop build can also pair as a client to another Windows, macOS, or Ubuntu host over Tailscale; see desktop-to-desktop companion mode.

From source:

git clone https://github.com/milind-soni/OpenMausBot && cd OpenMausBot
pnpm install

pnpm dev:server    # harness server → 127.0.0.1:8799
pnpm dev           # app → http://127.0.0.1:5199
pnpm dev:desktop   # Electron shell; keep the two commands above running

Requirements: macOS, Windows, or Ubuntu 24.04 x64, Node 24+, pnpm, and at least one agent CLI — claude, codex, or grok — installed and logged in. They appear in the model picker automatically.

Package the desktop application:

pnpm package:mac      # macOS: DMG + ZIP; requires Swift/Xcode tools
pnpm package:win      # Windows: installer + ZIP
pnpm package:linux    # Ubuntu x64: .deb + AppImage + verified CUA runtime

The Linux preview is user-initiated and never enables local bot control or Auto routing. On Xorg, the reviewed Cua Driver 0.19.3 runtime starts only after explicit opt-in and without its full-screen cursor overlay. On Wayland the app never starts it and clears legacy opt-ins while that real-seat safety gate remains unresolved. Chat, preview, Cloud, and Local VM remain available on both sessions. See the Ubuntu Desktop guide and tracking issues #29, #345, and #113.

The Linux packager downloads only the tag-pinned upstream archive during the build, verifies its size, SHA-256, complete member allowlist, and inner executable hashes, then packages only the CLI and cursor-theme sidecar. The installed app never downloads or self-updates native automation code. Cua's MIT notice, Inter's SIL OFL, a generated third-party license report, and a CycloneDX inventory ship with the runtime. See third_party/cua-driver/ for the reviewed provenance record.

These credentials are optional — local chat works without them. Paste a key once in App Settings (gear in the sidebar footer) when you want to enable its integration:

Composio and Boat are third-party services with their own accounts and terms. Boat is a paid service after its trial, and using a cloud computer may incur charges.

pnpm typecheck     # app + server
pnpm test          # unit, driver, API, and desktop capability tests
pnpm build         # typecheck + production build
pnpm check:electron # syntax-check Electron main/preload files
pnpm package:win   # Windows installer + zip → release/
pnpm package:linux # Ubuntu x64 .deb + AppImage → release/

Routines can run once, on selected weekdays, or every 5–1,440 minutes, using either a MAUS's configured model/computer or the Cloud VM runner. Interval schedules stay aligned to their chosen start time and skip an occurrence when the previous run is still active, so slow work cannot build an unbounded queue. A separate optional Advanced run limit can safely stop stuck work; no timeout is imposed unless one is chosen. The existing duration field remains calendar/display metadata. Webhook triggers are independent from schedules but reuse the same queued task executor and calendar receipts.

OpenMausBot starts a webhook-only receiver on 127.0.0.1:8800 by default (or one port above OMB_PORT). Set OMB_WEBHOOK_PORT to choose another port. A webhook secret is shown once when the trigger is created or rotated. Bearer authentication is recommended so the secret stays out of request URLs and most access logs; a single capability URL remains available for senders that cannot configure headers. The receiver exposes only /health and secret /hooks/... endpoints; it never exposes the app's broader API. OpenMausBot must remain running to accept a delivery. For public internet delivery, proxy only this dedicated receiver through a hosted relay or a tool such as Tailscale Funnel.

Early but real — the loop works end to end: message → agent → streamed reply → tools → approvals → computer use. macOS, Windows, and Ubuntu 24.04 x64 have released builds; Ubuntu remains a beta with the capability limits above. Rough edges to expect: hosted/mobile connectivity is still being built, and webhook triggers currently use the local receiver rather than an always-on hosted relay. Hosted voice needs an ElevenLabs, Fish Audio, or xAI key; built-in Mac and local Chatterbox voices need no cloud key. Calls are macOS-only for now (they ride the same on-device dictation as the composer mic) — see docs/voice-mode.md for the design and the known gaps.

Contributions welcome — the driver SPI in server/contracts.ts is deliberately small; adding a provider is one file in server/drivers/ plus a one-line registration. No code needed at all for your own engines: any ACP-speaking CLI or OpenAI-compatible endpoint plugs in through config — see docs/custom-engines.md. Users can add their own MCP tool servers with zero code via docs/custom-mcp-servers.md. To run bots on OpenRouter, Fireworks AI, DeepSeek, Cline or your own OpenAI- or Anthropic-compatible provider, see Other model providers.

OpenMausBot is free and open source. If it does real work for you, you can support its development through GitHub Sponsors with a one-time contribution or a monthly sponsorship. Your support helps fund ongoing development and maintenance; OpenMausBot remains free and open source.

With Node 24 or newer, install once and run:

npm install -g openmausbot
openmausbot

Or use npx openmausbot without a global install. First launch guides you with arrow-key choices: choose AI access, sign in or paste a hidden API key, choose a model, and optionally connect a phone. Next time, the same command reuses your saved setup and opens OpenMausBot on this computer. Keep the terminal open; Ctrl-C stops the server, not your saved work. Use --no-open to skip opening the browser.

Phone access is optional and defaults to skipping. Choose an explicitly approved managed public HTTPS endpoint protected by pairing, an existing Tailscale connection, or your own HTTPS reverse proxy. Both native apps pair from this flow: the QR is an app link when you are connecting an Android phone, and the iOS app takes either that or the web link. A browser works on either phone. A phone cannot use a localhost link. --local ignores saved remote access for one launch; --no-pair suppresses phone prompts and invitations but does not disable a saved remote connection.

The web UI can also be installed from Safari or Chrome as a standalone phone app. See Install the phone web app for Home Screen installation and pairing.

Run openmausbot setup to reconfigure without resetting bots or conversations; the saved model default applies only to new bots. Native setup confirms provider sign-in; API setup asks before a potentially billable test message. API keys are saved as plaintext, not encrypted, in private config.json (0600 on Unix). See the short setup guide for account differences, phone choices, credential storage, and cancellation.

For a background service on a VPS or an always-on computer, use npx openmausbot serve with explicit remote options: --tunnel after npx openmausbot login for a managed public address, --tailscale for your tailnet, or the Docker stack for your own domain. These are separate from AI-provider sign-in. Devices pair once with a short code. The deployment guide is docs/deploy-vps.md; the reference is docs/self-hosting.md.
