The implementation uses jextract-generated bindings, so it can be considered a light-weight wrapper around libghostty and a rendering layer that uses JavaFX. Works on Windows too (unlike Ghostty :P)

And for Clojurists that use Cljfx, I also made https://github.com/cljfx/ghosttyfx — a wrapper that exposes GhosttyFX as a reactive view.
