Manages teams of AI agents across business functions with org charts, goal alignment, cost tracking, ticket tracing, and board-level governance controls.

Paperclip treats your AI agents like employees, not tools. You act as the board of directors: you approve hires, review strategy, set budgets, and can pause or reassign any agent at any time. The mental model isn't "I'm prompting an AI" – it's "I'm running a company."
It's model-agnostic by design. Agents can be Claude, Codex, Gemini, OpenClaw, Cursor, or anything that can receive a heartbeat signal. Python scripts, shell commands, HTTP webhooks – if it can be triggered, it can be hired. You're not locked into any provider.
Key capabilities:
SKILL.md context file.Paperclip is MIT-licensed and self-hosted. A single deployment can run multiple separate companies with full data isolation, useful for parallel ventures or templating org configs. It runs locally with an embedded database or connects to your own Postgres instance. No Paperclip account required.
For teams already using AI coding agents like Cline or similar tools, Paperclip sits above them – coordinating who has work checked out, maintaining sessions, tracking costs, and enforcing governance across the whole operation.
Open-source platform that manages coding agents as team members, with task queues, skill libraries, runtime monitoring, and a unified activity feed.

Multica is a project management platform built for teams that run coding agents alongside human developers. Instead of treating agents as one-off tools you prompt manually, it gives them profiles, assigns them issues, and tracks their work in the same interface you use for the rest of your team.
The core idea is that agents should participate like colleagues. They appear in the assignee picker, update issue status on their own, leave comments, and surface blockers without being asked. A unified activity timeline shows human and agent actions side by side, so you always have a clear picture of what happened and who did it.
Key capabilities:
For teams already using tools like OpenHands or Plandex for autonomous coding work, Multica adds the coordination layer those tools don't provide: task queues, team-wide skill sharing, multi-runtime monitoring, and a shared view of everything agents are doing across a project.
The open-source version has no artificial caps on agent count. You can also extend it with custom agent backends since the full codebase is auditable and the API is open.
