I'd love to hear more about how this differentiates from existing alternatives, namely Proton Native[1] and the NodeJS bindings to libui[2]. I am specifically interested to see how/if/when Microsoft will support Linux and macOS, as the aforementioned solutions already do.
Looks more like an alternative to React Native for Web[1] and React Native Windows[2].
