cmux

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

bunx cmux or npx cmux

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

Each agent runs in its own Docker container, launching VS Code with a Git diff UI and a terminal for its CLI.
