boo is described as 'A GNU screen style terminal multiplexer built on libghostty (libghostty-vt), written in Zig' and is an app in the os & utilities category. There are more than 10 alternatives to boo for a variety of platforms, including Linux, Mac, Windows, Rust and Cygwin apps. The best boo alternative is tmux, which is both free and Open Source. Other great apps like boo are WezTerm, GNU Screen, RMUX and Waffle Terminal.
tmux is a terminal multiplexer: it enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.
