Which one, for what

Mistral Vibe CLI B

Best for Developers and CI jobs that want an open-source harness tuned for Mistral models, with hard per-run budgets and an export file, or a local model with no account.

Ahead on

  • Reliability, 69 against 60
  • Agent ergonomics, 84 against 77
  • Payments & pricing, 60 against 50
  • Transparency & trust, 80 against 59

Watch for

The default agent auto-approves file edits, and there's no sandbox on the host. Isolation needs the experimental --agent-socket server or a container

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

  • Schema & documentation, 90 against 76

Also in its favour

  • Runs on your own machine

Watch for

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

Verdicts

Mistral Vibe CLI

Apache-2.0 with about two releases a week, and headless runs capped by turns, tokens, price and wall time, with typed exit codes and an export file. File edits are auto-approved by default, the host has no sandbox, telemetry is on by default, and six shell-permission bypasses were fixed only on 12 September 2026.

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.

Before you call either

Mistral Vibe CLI

  1. Pass --agent on every -p run (plan is read-only). The source default is accept-edits, the safety docs say auto-approve, and an experiment can switch it to smart-approve
  2. Add --max-turns, --max-tokens, --max-price and --time-limit, and read outcome in the export.json that --output-dir writes. Exit 3 means a limit or a refusal
  3. Run in a container or behind --agent-socket before using --auto-approve. Vibe has no sandbox of its own on the host
  4. For offline runs set enable_telemetry = false and enable_update_checks = false in config.toml. The docs' enable_auto_update isn't the key the code reads
  5. Use 2.25.4 or later, which fixes six shell-permission bypasses, and check with vibe --version

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

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
