Which one, for what

OpenMausBot B

Best for A person or an outside agent who wants several CLI agents (Claude Code, Codex, Grok, ACP CLIs) organised as named bots with their own computers, routines and approvals, driven by MCP or a CLI.

Ahead on

  • Reliability, 60 against 45
  • Schema & documentation, 90 against 30
  • Agent ergonomics, 77 against 5
  • Security & auth, 59 against 36
  • Payments & pricing, 50 against 30
  • Maintenance & community, 74 against 58

Also in its favour

  • Runs on your own machine
  • Open source

Watch for

New bots start at Full access, which approves provider permission requests without a card

Unstoppable F

Best for A developer who runs Claude Code, Codex and Cursor on existing plans and wants parallel worktrees, pipelines and phone check-ins in one app.

Also in its favour

  • No key needed to call it

Watch for

No API, MCP server, SDK or documented CLI for an outside agent. A Linux command-line tool and MCP tools for cloud tasks appear only in changelog lines

Verdicts

OpenMausBot

A bounded 20-tool MCP server with typed schemas, annotations and idempotent sends, and a headless CLI with JSON output and exit codes, let another agent hand work to a bot team and wait on it. New bots start at Full access, so provider permission requests pass without a card, and usage analytics stay on until switched off.

Unstoppable

Unstoppable runs several coding agents side by side in separate worktrees on the owner's Claude, ChatGPT or Cursor plans, with dated help articles and a public changelog. It has no API, MCP server or documented command an outside agent can call, every chat starts in Full access, and its pages disagree on which parts need a paid plan.

Before you call either

OpenMausBot

  1. Ask the owner for a pairing code from Settings > Phone, exchange it at POST /api/auth/pair, and set OPENMAUSBOT_TOKEN with an explicit OMB_PORT
  2. Pass a send_id with every send_bot_message and send_channel_message, so a retry returns the first receipt
  3. Use wait_for_conversation instead of polling, and on needs-user stop and tell the owner a card is waiting
  4. Check a bot's access level with the owner before sending work. New bots run at Full access unless defaults were changed
  5. Ask the owner to switch off Settings > General > Usage analytics if nothing beyond model calls should leave the machine

Unstoppable

  1. Don't plan to drive Unstoppable from another agent. It has no documented API, MCP server or CLI. Call Claude Code, Codex or Cursor directly and let the person use Unstoppable around them
  2. Inside Unstoppable, check the approval mode before acting. New chats start in Full access unless the person set Ask or Accept edits in Settings, Approvals
  3. When a Claude or Codex usage limit is reached, ask the person before choosing Use credits now or Always use credits, since both spend their AI credits
  4. Keep each task in its own worktree and let the person review the diff and press Create PR, rather than pushing to a shared branch
