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.
Meta-harness that sits above Claude Code, Codex, and other AI agents to add policy enforcement, sandboxing, and real-time collaborative sessions.

Omnigent sits between you and the AI agents you already use. Instead of locking you into one harness, it wraps tools like Claude Code, Codex, and agents you write yourself inside a uniform session layer. Swap or combine them with minimal changes, no rewriting.
It's aimed at developers and teams who want more control over how agents behave, what they can access, and how much they spend. The core value is governance at the meta-layer rather than through prompts.
Key capabilities:
The architecture splits into two parts: a runner that wraps any agent in a sandboxed, uniform session, and a server that adds policies and shared history. Sessions are accessible through the terminal, a web interface, a native app, mobile, and a REST API.
For teams using tools like OpenHands or Cline alongside proprietary agents, Omnigent offers a single control plane rather than managing each harness separately. Licensed under Apache 2.0.
