...Ghostty provides fully standards-compliant emulation, drawing on ECMA-48 and xterm conventions, to ensure compatibility with existing shells and software, while its multi-renderer architecture leverages OpenGL (with ligature support) to sustain smooth rendering up to 60 fps under heavy load and minimal I/O jitter via a dedicated I/O thread. It offers modern windowing capabilities such as multi-window, tabbing, and splits, and embraces native platform experiences through SwiftUI and GTK4, all built atop a shared core written in Zig (“libghostty”) that can be embedded via a C API. Users benefit from basic customizability (fonts, backgrounds, colors), an opt-in feature set for interactive CLI tools, and performance competitive with leading terminal emulators.
