OpenMausBot is the open Grok Bot: a chat app of agents running on CLIs you already pay for
Four closed personal-agent apps shipped in about seven weeks, and the open-source answer is now trending on GitHub. OpenMausBot added 1,986 stars on Saturday, sits at 16,881 total, and shipped release v0.1.148 the same evening. It's Apache-2.0 and describes itself plainly as "the open-source Grok Bot alternative".
The idea is a Telegram-style chat app where every contact is an agent. Each bot has its own personality, model, computer and connected apps. The trick is that bots run on the claude, codex and grok command-line tools already installed on your machine, using your existing logins and subscriptions. No new account, no proxy. A small harness server on 127.0.0.1 owns every agent process, so transcripts and keys stay local.
Bots get hands through a cloud Linux desktop, an isolated local VM, or your own computer on macOS and Ubuntu Xorg after explicit opt-in, plus 500+ apps through Composio. Risky shell and file actions come back as approval cards before they run. Teams of bots install from a Markdown file, and the README says packages never carry credentials, conversations, permissions or memory.
Why this matters: Grok Bot, Meta Muse, OpenAI dots and Cue by Manus all keep the model, the computer and your data on the vendor's side. OpenMausBot keeps the shape and moves the line. If you already pay for Claude and Codex, the marginal cost of a whole team of agents is close to zero. The catch is that you inherit every CLI's quirks and rate limits, and an approval card is only as good as the person tapping it.
Two small red flags to note. Stars-per-day is a display number, and the README carries a loud warning that the project has no crypto token, which tells you somebody has already tried to sell one. Download from the repo, not from a link someone posted.
