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**Paperclip.** Board approvals, budgets with a hard stop and an activity log sit above whichever harnesses do the work, and eleven stable versions shipped in 90 days. The Claude Code and Codex adapters skip permission prompts and the sandbox by default, and twelve security advisories, five of them critical, have been published since April 2026.\n\n## Before you call either\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### Paperclip\n\n1. Set `PAPERCLIP_TELEMETRY_DISABLED=1` or `DO_NOT_TRACK=1` before the first start. Telemetry is on by default\n2. Set `dangerouslySkipPermissions` and `dangerouslyBypassApprovalsAndSandbox` to false on agents that read untrusted input, or run them in a sandbox provider\n3. Install with Node.js 24.11 or newer, and install and sign in to each harness CLI on the host first. Paperclip assumes they are there\n4. Use `--bind lan` or `--bind tailnet` at onboarding for anything beyond one machine. The default `local_trusted` mode treats every request as the board admin\n5. Treat 409 on task checkout as owned by another agent and pick different work. The API docs say not to retry\n\n## Questions\n\n### Which is better for AI agents, Muse Code or Paperclip?\n\nMuse Code scores 61.3 (C) on agent readiness against Paperclip's 59 (C), and leads in 3 of 7 scored categories. Paperclip leads on reliability, payments \u0026 pricing and transparency \u0026 trust.\n\n### Are Muse Code and Paperclip open source?\n\nNo open-source release is listed for Muse Code. Paperclip is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/muse-code-vs-paperclip.json, and with the fewest tokens: https://www.anchorterminal.com/compare/muse-code-vs-paperclip.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"muse-code\", \"b\": \"paperclip\"}`.
