The fastest workflow for developing with AI
agent-manager is a powerful, all-in-one workflow tool designed for developers working with AI models like Claude Code, Codex, OpenCode, Gemini CLI, Grok, and Pi. It consolidates multiple AI sessions into a single tmux interface, providing real-time status updates for each session. Its innovative features include the ability to unblock agents without attaching, fork conversations into named siblings, pin shells next to agents, and visualize file diffs with integrated review prompts.
