What are people using for full stack web in kotlin? A friend of mine wants to try and I don't want him to have a bad experience. I know compose for web is experimental right now. Last time I used the MUI/React wrappers it was a bit janky, but maybe its better now that was several years ago. I also saw this but I'm not sure if it's stable in practice: https://kobweb.varabyte.com/

I have been using the Kotlin MUI/React wrappers and had a pretty positive experience. Performance has always seemed same for me as with normal React/MUI. I have nothing against Kotlin-first frameworks: but sometimes being able to use the existing React Components is helpful (e.g. I was able to put in place wrappers to use existing React components like Rich text editors, drag/drop, etc). I have also used the TanStack infinite query functionality to manage paging / virtual windows (like LazyColumn)
