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.

Experiment! My past experiences with different terminal emulators

This is the same issue, as with Linux distributions. I understand one, two or three completely different terminals, to cover all use cases. But do we really need like 30 or 40 different emulators, 90% of them being in Alpha, or shouldn’t we consolidate the little development power we have, by putting it onto 3 to 5 major emulators, of which all are mature and mostly bug-free, as well as secure?

I use Wezterm on both Windows and Linux.

I’ve been running Rio for several weeks and like it. Maybe its too new for comparisons like this?

Coming from xfce4-terminal I was fiending for tabs, and that’s how kitty won
