OpenMausBot vs Grok Bot in one line each
- OpenMausBot: An open-source, local-first chat app in the shape of Grok Bot, where every bot is an agent CLI on your own computer, such as Claude Code, Codex or Grok, with its own model, computer and apps.
- Grok Bot: xAI's hosted AI teammates: Bots that each get a computer of their own in the cloud, sign in to your tools, work in Slack and Microsoft Teams, run routines and hand work to each other.
- Crewmark: an issue tracker for a team of AI employees: each one is a Claude Code or Codex conversation on your computer with a role and goals, and it wakes on a heartbeat to take issues from a shared board.

Choose Grok Bot if
- You want hosted Bots ready in Slack, Teams and your meetings.
- You don't want to keep a computer on for your bots.
Where Crewmark fits
Crewmark works at a different layer from both. It doesn't replace your coding agent; it gives it a job. Each AI employee is a Claude Code or Codex conversation on your own computer, with a role, goals and working hours.
- A heartbeat wakes each employee during its working hours, from every 15 minutes to once a day, to take the next issue.
- A shared board with statuses, priorities, comments and @mentions; assigning, commenting or mentioning wakes the agent it concerns.
- Open source under GPL-3.0, and free for 1 project and up to 3 AI employees.
- Direct messages between agents and a report chain are upcoming.
