Every bot gets a computer
In the free app: a cloud desktop from a provider you connect, spun up on its own with a live screen preview. Or point the bot at this Mac.
The open source Grok Bot alternative. Free and open source. Bring your AI account or API key. Provider fees and limits apply.
From download to your first useful task.
Start with one bot and one provider. No connected apps or cloud computer needed.
Download the desktop app
Choose your computer’s installer and open MausBot. The phone apps are companions; start on your computer.
Connect one provider
Use the onboarding engine check to install and sign in to one supported agent, such as Claude Code or Codex. Follow its install or sign-in instructions, then check again. You can also find this in App settings → Agent engines.
Create your first bot
Select New or share → New bot. Give it a name, choose the connected engine and an available model. A working folder is only needed for tasks involving files.
Send a small, useful task
Ask your bot to plan your day, summarize notes, or draft an email. Start with one clear request and review its answer.
Work with a whole team of bots
Give each bot a job, a brain, and a computer. They run in parallel on your own machine, and come back when something needs you.
Pick a brain per bot
Claude and Codex side by side, defaults marked. Switch a bot's model mid-conversation.
Connected apps
Gmail, Slack, GitHub, Notion, Linear and hundreds more over Composio. OAuth once, every bot can use them.
Manage bots like chats
Pin, mark unread, duplicate, hide, delete. It's a messaging app, and your agents behave like contacts.
Bots that talk back
Hit call and it's a conversation. It hears you, narrates its work, and asks for approvals out loud. Live calls work on every plan, with your own OpenAI key.
Keys once, everything lights up
Paste credentials once and the provider fleet hot-reloads. Add a treg key and bots research X, companies, people, trends and search results. Secrets are write-only.
Automations from one sentence
Say “when I get an email from Acme, draft a reply” and it's set up: on a schedule, on a webhook, or when something happens in Gmail, Slack, HubSpot or Stripe. Gmail is checked every 15 minutes, other apps within seconds.
How it works
Your agents, your machine
Bots run on the claude, codex, and grok CLIs already installed on your computer, using your logins and your subscriptions, with no proxy in the middle.
One local harness
A single server on 127.0.0.1 owns every agent process and normalizes each provider's native protocol into one event stream.
Nothing leaves unless you send it
Transcripts, keys, and events live in ~/.openmausbot on your own disk. Local-first is the default, not a setting.
Give each bot a job worth doing.
Pick a job to see what its bot reports back, and what it waits for you to approve.
Finds the deals that went quiet, works out who owes the next step, and drafts each follow-up. Nothing sends until you approve it.

A concept from MausBot
MausBox
Sovereign AI for knowledge work.
A small silver box that runs MausBot and open models at home, with 128 GB of memory, so your files and chats stay with you.
What you get on each Cloud plan
The app is free. A Cloud plan gives your bots their own cloud machine, so they keep working with your laptop closed.

*An estimate, not a limit: a bot at work uses about 0.5–1 GB of memory, so this is roughly how many can work at the same moment.
Allowances reset on the 1st of each month (UTC). A small computer counts as half an hour. Bring your own Claude or ChatGPT account, or an API key. Model usage is billed by your provider.
A few things to know before you start.
What is free, and what do I pay for?
The MausBot desktop and companion apps are free and open source under Apache 2.0. Model usage is separate: bring a supported provider account or API key. Your provider’s pricing, usage limits, and terms apply. A subscription to one provider does not include access to other providers. Cloud hosting and some optional services cost extra.
Which platforms can I use?
Desktop downloads are available for macOS (Apple silicon and Intel), 64-bit Windows, and x86-64 Linux (.deb and AppImage). Android and iOS have companion apps, shared in our Discord. See the download page for platform requirements and installation steps.
Do I need to connect Gmail, Slack, or a cloud computer?
No. You can start by chatting with a bot using one connected provider. Connect an app or enable computer access only when a task needs it. Those integrations can have their own accounts, permissions, and charges.
What can a bot access, and when does it ask for approval?
Access depends on the engine, working folder, connected apps, and computer permissions you enable. Supported actions can show approval requests in chat. Review the requested action before allowing it; approval coverage depends on the engine and tool, so it is not a guarantee that every action will pause. Start with a small task and a dedicated working folder.
Is my data local or in the cloud?
The desktop app keeps local conversation and workspace data on your computer. Your prompts and relevant context are sent to the model provider you choose; connected apps receive the data needed for their actions. A Cloud workspace stores and processes its workspace data on the hosted server. Local storage does not mean model requests stay on your device.
Does the phone app run my bots?
The phone app is a companion that connects to the computer or server hosting your bots. For the free desktop setup, keep MausBot open and your computer awake and connected to the internet. Pairing a phone does not move your bots to the cloud.
What happens when my computer is off?
Bots hosted on that computer cannot work while it is asleep, offline, or shut down. To keep working independently of your laptop, you need an always-on host, such as a separately configured server or the optional paid MausBot Cloud workspace.
Where can I get help?
Start with the installation instructions on the download page. For questions, join Discord support. For reproducible bugs, open a GitHub issue with your operating system, app version, and steps to reproduce. Remove credentials and private content before sharing logs or screenshots.
