Is Alacritty or Kitty faster?

Both are GPU-accelerated and extremely fast. Alacritty is often cited as the fastest terminal emulator due to its minimalist design and no extra features beyond rendering. Kitty is also GPU-accelerated but slightly more feature-rich, which adds marginal overhead. In practice, both are faster than most users will ever need.

What is the difference between Alacritty and Kitty?

Alacritty is intentionally minimal — no tabs, no splits, just fast terminal rendering. It relies on tmux or a multiplexer for those features. Kitty has built-in tabs, splits, image protocol, and font features while remaining GPU-accelerated. Kitty is more batteries-included; Alacritty is pure speed with minimalism.

Who Should Choose What?

→ Choose Alacritty if:

You want the absolute fastest terminal with zero unnecessary features. You already use tmux for window management and don't need built-in tabs. You work on Windows, macOS, and Linux and want one terminal everywhere. You appreciate minimal, composable tools.

→ Choose Kitty if:

You want GPU speed with built-in tabs, splits, and image rendering. You use Neovim or terminal tools that display images and need the Kitty image protocol. You want advanced font rendering with ligatures. You work on macOS or Linux (not Windows).

Frequently Asked Questions

Should I use Alacritty with tmux?

Yes — Alacritty is intentionally designed to be used with a terminal multiplexer like tmux or zellij for tabs and splits. This composable approach means Alacritty stays minimal and fast while tmux handles session management. Many developers love this Unix-style "do one thing well" approach. If you'd rather not learn tmux, Kitty gives you those features built-in.

Does Kitty work on Windows?

No — Kitty does not support Windows. It works on macOS and Linux only. Alacritty supports Windows, macOS, and Linux. If you need a cross-platform terminal on Windows, Alacritty, Windows Terminal, or WezTerm are better choices.

Editor's Take

My team tested both Alacritty and Kitty for a month each. The surprising winner? It came down to one thing — customer support. When things broke (and they always do), the tool with better support won.
