MausBot

MausBot is an open source Grok Bot alternative that gives you your own team of AI bots inside a familiar chat app, running on your own machine. Instead of a single assistant, MausBot lets you give each bot a job, a brain and a computer: bots run in parallel on your computer and come back when something needs you. The app is free and open source under Apache 2.0, available for Mac, Windows and Linux, and it works with your own provider account or API key, so provider fees and limits apply. Its stated purpose is putting your business on autopilot across areas such as business, sales, support, hiring, invoices and SEO. MausBot is designed for people who want agentic AI teammates doing real work in a chat interface they already understand, while keeping their own machine, logins and subscriptions at the centre. The problem MausBot addresses is the sense that AI agent software usually arrives as another hosted subscription. In the words on the site, MausBot is the open source Grok Bot alternative, and the builders describe making an open source version of the Grok Bot complete with all the features. The stated claim is that it does not need any subscriptions at all and instead uses the existing subscriptions you already have. Users quoted on the page frame the same point, arguing that nobody wants another monthly seat and that intelligence on your machine should come with your machine, not be billed like headcount. MausBot's answer is local-first by default: transcripts, keys and events live in ~/.openmausbot on your own disk, and nothing leaves unless you send it. The core capability is giving each bot a job, a brain and a computer. In the free app, every bot gets a computer in the form of a cloud desktop from a provider you connect, spun up on its own with a live screen preview, or you can point the bot at your Mac. Each bot also has its own brain: Claude and Codex are shown side by side with defaults marked, and you can switch a bot's model mid-conversation. Supported models listed on the site include Claude from Anthropic, Codex from OpenAI, Grok from xAI, Cursor, Kimi from Moonshot AI, Droid from Factory, Antigravity from Google, OpenCode, Qwen from Alibaba, Hermes from Nous Research and Pi. Because the brain is chosen per bot, different bots in the same team can think with different models while living inside one chat app, which lets you match a model to the nature of the work rather than accepting one engine for everything. Connected apps give bots hands. MausBot offers Gmail, Slack, GitHub, Notion, Linear and hundreds more over Composio: OAuth once and every bot can use them. Credentials are handled through a keys screen where you paste credentials once and the provider fleet hot-reloads, while secrets are write-only so the UI never sees them. Routines sit on a calendar, with every bot's routines placed on one week so you can see what runs when, plus a next indicator for the upcoming run. Bots can also talk back: hit call and it becomes a conversation, where the bot hears you, narrates its work, and asks for approvals out loud, with Approve and Not now controls on screen. MausBot manages agents the way a messaging app manages contacts. You can pin, mark unread, duplicate, hide and delete bots, and the site describes the product plainly: it is a messaging app, and your agents behave like contacts. Bot rows show their latest activity, such as reminders sent, a plan ready, a launch draft delivered or pull requests reviewed. On top of that sits a catalogue of jobs worth giving a bot: Sales Follow-up, Chief of Staff, Recruiter, Bookkeeper, Bug Fixer, Support Triage, Competitor Watch and SEO Growth. Each job lists when it runs and which tools it uses, and each is designed so the bot reports back and waits for your approval before anything goes out. The approach is deliberately local. 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. A single local harness, one server on 127.0.0.1, owns every agent process and normalizes each provider's native protocol into one event stream, which is what allows different engines to appear uniformly as bots in the app. Nothing leaves unless you send it: transcripts, keys and events live in ~/.openmausbot on your own disk, and the site states that local-first is the default, not a setting. Getting started follows a short path: download the desktop app, connect one provider through the onboarding engine check, create your first bot with a name, engine and model, then send one small useful task. The outcomes described on the site follow from that design. Because bots run in parallel on your own machine and come back when something needs you, work proceeds without you driving each step, while approvals keep you in control of what actually gets sent, merged or prepared. Running on existing subscriptions removes a barrier for adopters, and testimonials highlight that the bots, the machine and the keys are yours. Others point to configuration flexibility, cross-agent capability, and the option to run on your own infrastructure, for example on an Azure VM for an always-on agent, or with only your own local models and your own agent computer. A contributor notes the merged MCP server for external agent orchestration, which lets one agent communicate with the rest, and another notes that dynamic personality makes the agent experience feel more alive. Concrete use cases come straight from the job catalogue. Sales Follow-up finds the deals that went quiet, works out who owes the next step and drafts each follow-up, running weekdays at 9:00 AM with Gmail and HubSpot, and nothing sends until you approve. Chief of Staff reads your inbox, calendar and team channels before your day starts and sends one brief covering what changed, what is waiting on you and what it can clear, weekdays at 7:30 AM with Gmail, Google Calendar and Slack. Recruiter finds people who fit an open role, checks each one against your must-haves and keeps a shortlist with the reason they made it, using its own browser and Google Sheets. Bookkeeper pulls overdue invoices, drafts a polite reminder for each one and keeps a running sheet of who owes what, with Stripe, Gmail and Google Sheets, running Mondays at 9:00 AM. Bug Fixer reproduces the bug, writes a test that fails for the same reason, fixes it and prepares a pull request with the evidence. Support Triage answers the questions you have answered a hundred times and turns technical ones into tickets, while Competitor Watch checks pricing pages, changelogs and docs and writes a short brief, and SEO Growth turns search data into a short list of fixes and content briefs. MausBot is for individuals and teams who already pay for AI subscriptions and want agentic teammates running on their own hardware, from solopreneurs running daily operations with an autonomous AI team on a laptop, to developers working with coding agents, to teams wanting shared always-on automation. Integrations named on the site include Gmail, Slack, GitHub, Notion, Linear and hundreds more through Composio, with computers and apps from Cua, ASCII Box and Daytona, and models from Anthropic, OpenAI, xAI, Cursor, Moonshot AI, Factory, Google, OpenCode, Alibaba, Nous Research and Pi. Pricing is straightforward: the desktop app is free and open source under Apache 2.0 for Mac, Windows and Linux, phone apps are companions that start from your computer, and Cloud plans start with a 3-day free trial that you can cancel any time. Bring your own provider account or API key, and provider fees and limits apply. MausBot's primary value proposition is simple: a whole team of AI bots, each with a job, a brain and a computer, living in a chat app on your own machine. It is free, open source under Apache 2.0, built on the CLIs and subscriptions you already have, and local-first in the way it stores transcripts, keys and events. For anyone who wants real work done by agents, from sales follow-ups and daily briefs to invoices, bug fixes, competitor monitoring and SEO, without adding another hosted subscription, MausBot is the open source Grok Bot alternative that keeps your bots, your machine and your keys in your hands.
