Agent Manager

Agent Manager is a terminal user interface, written in Go and running on top of tmux, that lets a developer run many AI coding agents side by side and control them from a single list. Each row is a real tmux session running the developer's own installed command line agent, with its existing login, configuration and MCP servers, so the manager never wraps or reimplements the agent itself. It is built for developers who keep several coding agents busy at once across one or more projects. Nine CLIs ship with status detection out of the box: Claude Code, OpenCode, Codex, Grok Build, Gemini CLI, Pi, Command Code, Hermes Agent and Muse Code. A prompt bar spawns a new agent from a single sentence with the project directory already set, and the same key sends a reply to an agent that is blocked without attaching to its pane. Sessions rename themselves once the agent understands the task, work can be spawned into a fresh git worktree, and a whole file diff reviewer sends line comments back into the agent. Through MCP, agents can also spawn other sessions, read their screens, message them and wait on them, with file claims that surface edit overlaps before either commits. Agent Manager is free and open source under the Apache 2.0 licence, and there is no paid tier or pricing page. It installs through Homebrew and runs on macOS, Linux and WSL; any model or subscription costs belong to the agents you already use. The project is built by Yoan Wai, with the source, issue tracker and releases in a public GitHub repository.
