Ghostty

A GPU-accelerated terminal emulator by Mitchell Hashimoto (co-founder of HashiCorp). Written in Zig, with platform-native UI on macOS and Linux.

Key features: native macOS integration (splits, tabs, fullscreen behave like a real Mac app), GPU rendering via Metal/OpenGL, fast text throughput (competitive with Alacritty), and modern features. Config is a single plain-text file.

I use it as my main terminal, with Herdr running inside it for agent sessions—see AI agents: how I use them.
