CCManager is a self-contained CLI application for managing multiple AI coding assistant sessions simultaneously. It supports Claude Code, Gemini CLI, Codex CLI, Cursor Agent, Copilot CLI, Cline CLI, OpenCode, and Kimi CLI. The tool runs sessions in parallel across Git worktrees, provides real-time state monitoring (busy, waiting, idle), and offers features like session data copying between worktrees, configurable keyboard shortcuts, command presets with fallback, and experimental AI-based auto-approval for safe prompts.
