Open source Claude Code manager that supports Codex/Gemini/Cursor/OpenCode/Amp CLI

cmux lets you spawn Claude Code, Codex CLI, Cursor CLI, Gemini CLI, Amp, Opencode, and other coding agent CLIs in parallel across multiple tasks.

Every run spins up an isolated VS Code workspace either in the cloud or in a local Docker container with the git diff view, terminal, and dev server preview ready so parallel agent work stays verifiable, fast, and ready to ship.

cmux supports macOS. Linux and Windows support coming soon.
