Not sure as I haven't done any work with it. On a cursory glance it could have some overlap but it appears to not target the 1st class UI frameworks. It looks to be a UI framework unto itself. So more of a Flutter than what we're doing is my very quick guess. We get major benefits from targeting the 1st class UI frameworks, primarily being we let them do the work. Developing a UI native framework I think is way way more effort than what we've done so we let Apple, Google, and Microsoft to decide what the desired user experience is on their devices. And we just allow our composable markup to represent those frameworks. A recent example of this is with the new "glass" iOS 26 UI update. We had our client updated for the iOS 26 beta on day 1 of its release. Flutter has to re-write their entire UI framework if they want to adapt to this experience.

Hyperview creator here. Yes, it sounds like the difference is that your project is directly rendering platform-native UI widgets, while Hyperview is built on top of React Native for the cross-platform layer.

Curious how you will handling the differences between platforms. For example, Android prefers top tab bars, while on iOS the convention is to put tab bars below the content.

This is one of the fundamental differences for what we're doing. We are not building a write-once-run-everywhere solution. SwiftUI will have its own templates, Jetpack (Android) will have its templates, WinUI3 will have its templates.
