The Modern Terminals Showdown: Alacritty, Kitty, and Ghostty Comparing Alacritty, Kitty, and Ghostty for Speed, Features, and Customization

Terminal emulators are software programs that replicate the functionality of old hardware terminals. Modern GPU-accelerated options like Alacritty, Kitty, and Ghostty offer significant performance improvements over traditional CPU-based terminals. Alacritty focuses on pure speed with minimal features, written in Rust with OpenGL rendering. Kitty balances performance with built-in features like tabs, splits, and image rendering, using C and Python. Ghostty, the newest contender written in Zig, combines speed with cross-platform native support and modern UX. Each uses different graphics APIs and configuration approaches, making the choice dependent on whether you prioritize raw speed, feature richness, or platform consistency.
