4 ways to reduce Kitty RAM usage
1 Skip tmux
Use Kitty's native tabs and splits instead of tmux — eliminates an entire process.
2 Tune scrollback
Configure scrollback_lines to 10,000 rather than unlimited.
3 Use kitten ssh
For remote sessions, kitten ssh copies your Kitty terminfo automatically.
4 Optimize latency
Set repaint_delay 6 and input_delay 1 for the lowest possible input latency.
How DevPulse helps with Kitty
DevPulse recommends Kitty for developers who want Alacritty-class performance with built-in tabs, splits, and image rendering.
Instead of guessing how much RAM Kitty consumes or manually checking Activity Monitor, DevPulse gives you a clear, always-visible answer in your menu bar.
