The agent runs shell commands in its container with no approval step, the web interface has no login by default, and five CVEs from the past year have no published GitHub advisory.\n\n**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.\n\n## Before you call either\n\n### Agent Zero\n\n1. Set a UI login and password in Settings before publishing the port or opening a tunnel. The default has none\n2. Fill `allowed_users`, `allowed_numbers` or `sender_whitelist` before enabling a channel. An empty list accepts every sender\n3. Enable the Infection Check plugin when the agent reads mail, web pages or MCP results. It ships disabled\n4. Run v2.12 or later. It fixes a Telegram webhook authentication bypass and a WhatsApp media path traversal\n5. Call `POST /api_message` with the `X-API-KEY` header. The token changes when the UI login or password changes\n\n### Muse Code\n\n1. Set `META_API_KEY` for headless runs. Browser sign-in isn't available in CI or for Meta Managed Accounts\n2. Gate on your own test command, not the exit code. `muse exec` returns 0 when the turn completes even if tests still fail\n3. Pass `--max-model-steps` on unattended runs so a stuck task can't loop\n4. 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\n5. Turn Contributor mode off in `/settings` before a subscription session touches private code\n\n## Questions\n\n### Which is better for AI agents, Agent Zero or Muse Code?\n\nMuse Code scores 61.3 (C) on agent readiness against Agent Zero's 54.2 (C), and leads in 4 of 7 scored categories. Agent Zero leads on reliability and payments \u0026 pricing.\n\n### Are Agent Zero and Muse Code open source?\n\nAgent Zero is open source (MIT). No open-source release is listed for Muse Code.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agent-zero-vs-muse-code.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agent-zero-vs-muse-code.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agent-zero\", \"b\": \"muse-code\"}`.
