AlacrittyvsKitty

The short version

Pick Alacritty if you want a terminal that does very little beyond rendering text quickly and predictably.

Pick Kitty if you want the terminal itself to be a serious platform with tabs, splits, graphics, remote tooling, and scripting.

The philosophical split

This comparison is really about where you want complexity to live.

Alacritty says complexity should live elsewhere: in tmux, Zellij, your window manager, or your shell setup. The terminal should be fast, correct, and mostly invisible.

Kitty says the terminal can be much more than that. Built-in layouts, the graphics protocol, kittens, remote control, and SSH helpers all make Kitty feel closer to a toolkit than a plain emulator.

Where each one wins

Alacritty wins when your ideal setup is already modular. If you like tmux, want the same terminal across multiple operating systems, and do not care about inline graphics, it remains an excellent choice.

Kitty wins when you want capability from the terminal itself. Inline images, tabs, splits, layouts, and scripting are not edge cases there; they are part of the core product story.

That makes Kitty the higher-ceiling tool and Alacritty the lower-friction one. Neither philosophy is wrong. They just optimize for different kinds of terminal users.

Our recommendation

If you already think "tmux handles that," choose Alacritty.

If you keep wishing your terminal could do more on its own, choose Kitty.
