Could you build this?
No Building a custom GPU-accelerated macOS terminal emulator with advanced custom rendering (Liquid Glass UI) on top of Zig/Ghostty internals requires deep native systems programming, AppKit/Metal expertise, and terminal escape sequence plumbing.
What it would actually take: The architecture requires integrating with Ghostty's core terminal engine (written in Zig) and building custom macOS AppKit/Swift bindings with Metal or custom shaders to achieve glass-like UI effects while maintaining 60+ FPS terminal rendering, PTY management, and low-latency input processing.
Discussion
20 comments analyzed.
Competitors mentioned: ghostty, wezterm, iTerm2, Konsole, kitty
Concerns raised: Liquid Glass styling doesn't match Apple guidelines, Transparent UI makes text hard to read, Terminal content area doesn't properly support glass effect, Tagline mentions technical implementation instead of benefits, Obsession with transparency is unnecessary
Feature requests: Theme for iTerm2 instead of new application, Remove or improve titlebar design, Better accessibility when transparency effects disabled, Proper blur and opacity matching Apple's Liquid Glass
