Just had a look at Kitty and from what I understand, it's an emulator, and it's fast, has ligatures.
Since I rarely use terminal outside of VS Code, i.e. zsh shell on Mac, I don't quite understand what would I get from it?
Reviews say it's fast, has low latency between typing and the text appearing on the screen - I'm not seeing latency either way. The text is there, can it get any faster? 😅
Also, calling out the warning signs, my bar for a native platform experience is that the app feels and acts like a purpose-built native app. I don't think this bar is unreasonable. For example, I don't think it's unreasonable to say that Alacritty is kind of not native because new windows create new processes. Or that Kitty is kind of not native because tabs use a non-native widget. And so on (there are many more examples for each).
So nothing wrong with Kitty on MacOS e.g., but the "feel" is not native. Personally don't care too much about that, but the author seems to do.
As @Treeniks@lemmy.ml pointed out, the author considers something as small as spawning a separate process for each window to mean a "non-native experience" (wait till they see how web browsers work)
