Boo – screen-style terminal multiplexer built on libghostty

Boo is a terminal multiplexer for developers that uses libghostty to render each pane as a native screen-style window, offering seamless integration with the host OS. It targets power users who want the session management of tmux or screen but with modern GUI features like per-pane transparency, drag-and-drop, and native window decorations. Its interest lies in bridging the gap between traditional terminal multiplexers and full graphical interfaces without sacrificing performance or keyboard-driven workflows.
