Raycast are not building Mac apps the apple way though. They are using react native and I am willing to bet that this does too.

I always thought it was native. You can write extensions using React, yes, but I was under the impression those got compiled to their internal Swift-based UI components

Raycast could be both native and written with React Native:

React Native itself renders JSX as native components (not a web view that renders HTML/CSS).

People conflate React with HTML because that is the most common renderer, but React can be rendered into anything.
