Muse Code vs OpenMausBot

Muse Code

Muse Code runs with approvals and an OS sandbox on by default, per-host network approval, an append-only event log and a headless mode with documented exit codes. It is the only route to Muse Wonder Full. It is closed source with undated release notes and no free route, and subscriptions allow training on code unless Contributor mode is turned off.

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.

Muse Code

1. Set META_API_KEY for headless runs. Browser sign-in isn't available in CI or for Meta Managed Accounts
2. Gate on your own test command, not the exit code. muse exec returns 0 when the turn completes even if tests still fail
3. Pass --max-model-steps on unattended runs so a stuck task can't loop
4. Prefer --disable-approval to --yolo in CI so the sandbox stays on. On Linux the runner needs a working bubblewrap and a non-musl build
5. Turn Contributor mode off in /settings before a subscription session touches private code

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
