- More widely used (Gid Score 76 vs 23)
-
Open-source Node.js server and React app for running a team of AI agents toward a business goal. You define the goal, give agents such as Claude Code, Codex, Cursor, Gemini CLI, OpenCode or OpenClaw roles in an org chart, set a budget per agent and approve the plan, then follow tasks, costs and an append-only audit log from one dashboard. A hosted Paperclip Cloud is on a waitlist.
- Bring your own API key
- More widely used (Gid Score 58 vs 23)
- Growing fast: usage up 100% in 30 days
