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).
Okay sounds like nothing other than being "more native" than Kitty, but they will add more fearures later. I'm not convinced to switch, but I'm interested what Ghostty does in the future.
Ghostty is a terminal emulator that differentiates itself by being fast, feature-rich, and native. While there are many excellent terminal emulators available, they all force you to choose between speed, features, or native UIs. Ghostty provides all three.
