From download to your first useful task.

Start with one bot and one provider. No connected apps or cloud computer needed.

  1. Download the desktop app

    Choose your computer’s installer and open MausBot. The phone apps are companions; start on your computer.

  2. 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.

  3. 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.

  4. 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.

Full setup guide

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.

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.

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.

Hello from MausBot

The desktop app comes in 10 languages. It follows your computer's language, and you can switch any time in Settings.

  • English
  • Deutsch
  • Español
  • Français
  • हिन्दी
  • 日本語
  • Português (Brasil)
  • 简体中文
  • 繁體中文(台灣)
  • Українська

Some translations are still growing, so a few screens may show English for now.

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.

Can I try Cloud for free?

Yes. Every Cloud plan starts with a 3-day free trial, with $5 of Claude credit included. Checkout asks for a card, and your first payment is on day 4; cancel before then and you pay nothing. We email you a reminder 1 day before your first payment. The trial is one per person. The desktop app is free and needs no trial.

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.
