According to this this slideshow:

At a fundamental level, this is the state of terminal emulators today as I saw it. You have fast terminals, feature rich terminals, and native terminals. You can pick at most two properties to have.

Ghostty aims for – and in my opinion already achieves – all properties.

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).
