tmux

tmux is an open-source Terminal Multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window. It is useful for running more than one command-line program at the same time.

Using Tmux will add some overhead, but you won’t completely lose Ghostty’s performance benefits because:

1. Ghosty’s core optimizations will still apply:
   • The SIMD escape sequence detection
   • Fast Unicode decoding
   • Pre-computed code point width tables
   • Efficient memory layout
   • Fast rendering pipeline using Metal
2. However, Tmux does introduce an additional layer that:
   • Needs to process escape sequences again
   • Manages its own screen buffer
   • Has its own rendering cycle
