What it is

A terminal workspace manager, written as a single Rust binary, that keeps agent sessions running in a background server so you can detach, reconnect over SSH, and restore layouts after restarts. Each pane shows whether its agent is working, blocked, or idle, and local and remote machines appear in one combined agent list. Developers who run Claude Code, Codex, OpenCode and similar agents side by side use it to watch them all at once, and agents themselves can spawn panes and message each other through its CLI and socket API.
