help Kitty FAQ

Does kitty work natively on Windows?

Kitty officially targets Linux, macOS, and several BSD systems, not native Windows. Windows users commonly run it through WSL with a Windows display server or choose a native terminal such as Windows Terminal or WezTerm.

Is kitty configured with JSON?

No, kitty uses a plain-text file named kitty.conf rather than JSON. On Linux, the usual location is ~/.config/kitty/kitty.conf, and the configuration can define fonts, colors, layouts, shortcuts, and startup sessions.

Can kitty replace tmux for tabs and split panes?

Kitty has native tabs, multiple windows within a tab, layouts, sessions, and remote control, so many local tmux workflows can move directly into the terminal. Tmux remains useful when sessions must survive an SSH disconnection on a remote server.

What does GPU acceleration actually improve in kitty?

Kitty uses OpenGL to render text, moving much of the drawing work away from the CPU. This is especially noticeable with fast scrolling, large terminal outputs, ligatures, images, and several panes updating at once.
