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

UI-wise, I kinda like Ghostty more. It feels slightly more polished. However, I've moved to Kitty mainly because of its native session support. The only way to have sessions in Ghostty is through a multiplexer, which I'm not a fan of anymore.

Kitty renders some icons badly but ghostty doesn't. In a nutshell, kitty takes some rendering shortcuts that cause the bad rendering:

People like to say that kitty is performant, but I haven't found ghostty to be otherwise.

A significant differenciator is the dev/maintainer I'd say. No, really, hear me out :) I'd start with: this goes for almost any FOSS tool, not just this. Not saying one is good, one is not – but user choices, user feedback, interactions, deisgn goals/choices get affected (and sometimes influence) a lot based on how a dev/maintainer looks at their product and humans who use, or would use, their product – or contribute for that matter.

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).
