About Multica
Multica is an open source project management platform designed for teams combining human developers and AI coding agents.

The platform solves the problem of fragmented agent workflows: when using multiple AI tools like Claude Code, Codex, or Cursor in separate terminal sessions, context is lost between runs, coordination becomes manual, and oversight is difficult. Multica centralizes agent execution, assignment, and review into a single system where work flows from issue …
