What's this about?
A terminal UI (built on tmux) for running Claude Code, Codex, and OpenCode side by side, so you can supervise several coding agents from one cockpit.
What exactly is a "TUI"?
A TUI is a text/terminal user interface — a keyboard-driven app that runs in your terminal instead of a graphical window. tmux lets one terminal hold many panes at once, so this tool tiles several agents in view together.
