Agent Manager is a terminal UI that runs many AI coding-agent CLIs side by side, each in its own persistent tmux session, and shows them in one list with live status. It is a thin layer over the tools you already have installed: each session launches your own CLI as-is, so your login, subscription, configuration files, MCP servers, and the tool's own features carry over unchanged.
Sessions appear in a project tree that you can fold and reorder, with a preview of each agent's latest answer. You can send a prompt into any session without attaching to it, spawn a new agent in a group, revive a dead session on its own conversation, fork a conversation into a separate named session, or restart one on an empty context. Each session can start on its own model, reasoning effort, and profile, read from the CLI at runtime, and can optionally run in its own git worktree. Sessions live on a private tmux server, so they survive the manager quitting and never mix with your own tmux sessions.
A diff review panel shows a session's changes as full-file diffs, where you comment on lines and send numbered review rounds back to the agent. Shell terminals for builds and Git sit in the same list under an agent or group. Every MCP-capable session gets tools to spawn another agent, message it, and wait for it to finish. Agent Manager runs on macOS and Linux, and on Windows inside WSL2. Cost tracking is not yet available.
