Libghostty backend keeps saved state accurate
“boo swaps that layer for libghostty-vt, Ghostty's VT core, so the saved state matches what your terminal would actually display”
Comment from 11 Jun 2026 in “Show HN: Boo – screen-style terminal multiplexer built on libghostty” “Really dig the minimal approach here. Swapping the backend to libghostty is exactly the kind of clean architecture we need.”
Comment from 12 Jun 2026 in “Show HN: Boo – screen-style terminal multiplexer built on libghostty” Creative, inspired use of a game engine
“branching out and using something like a game engine for something like this is a fairly inspired choice”
Comment from 11 Sep 2026 in “Show HN: Godot and Rust based multiplexer (terminal panes and more)” “this is a very non-obvious, creative mashup of things that i directly found inspiring”
