CrewCode is a free, open-source control center for developers running multiple AI coding agents across real repositories. Unlike chat only agent tools, it makes the full workflow visible: launch agents in isolated git worktrees, supervise every lane in Mission Control, switch providers with context handoffs, review combined diffs, and merge with confidence. It supports CrewCoder, Claude Code, Codex, OpenCode, Ollama, and more on macOS, Linux, and Windows.
