I haven't try Ghostty, but what I like about kitty is that it's performant, easy to customize (often it's just one line to add and you get that new feature you want), I like their defaults for tabs, layouts. It's not overwhelming but not too minimal either. I just find it's a sweet spot. I also somehow like the personality of the maintainer which seem to have a nice vision for the project. My major gripe is that it's not available on windows, but anyways I rarely use microslop products nowadays.

Very similar, about the only difference from user perspective is that Kitty has a slight content 'wobble' on macOS when resizing the window (this typically happens when the content is rendered via an MTKView or CAMetalLayer and its parent view's 'layerContentsPlacement' isn't anchored to one side during window resizing). That would be trivial to fix though.

PS: another difference is installation size, on macOS Kitty is about 246 MB while Ghostty is 67 MB (and it looks like Kitty comes with a glslang shader compiler and python 3.14 frameworks, which together already take up 32 MB).

TL;DR: it feels like Ghostty is paying a bit more attention to platform-specific aspects than Kitty.

Also funny/sad: both call themselves 'cross-platform', but then don't support Windows (only various UNIX variants).

Ghostty UX feels more polished compared to Kitty. I tried Kitty for a while but just did not like the default UX.

I have the same SSH qualms. I still use it because there's not much better for what I need.

When I first used Calibre I thought it was a disorganised mess trying to cram too many features in one app.

Over time I learned to appreciate the vision: it’s not the stereotypical modern streamlined app, it’s the cockpit of a spaceship. It’s AutoCAD for ebooks. I really enjoy that application now, I haven’t even scratched the surface of its featureset.

I heard the author gets very defensive of his design choices: good, I wish we had more opinionated app developers in FOSS.

Windows Terminal. I used to use things like Kitty but don't see a need these days.
