Synthetic event system + render decoupling. Preact uses the event system of the platform (browser) and only renders to it (there's no react native support).

Anyway we are using it at prod and allowed us to reduce our bundle sizes ;)

Worth noting that while Preact specifically doesn’t support React Native, JSX does. So to the extent the dev APIs stay in line you can always swap out the underlying library for that target (or other renderers).
