Not Java, but close. With Kotlin, there is a version of Jetpack Compose (Android UI framework) ported for the Web. It's still experimental. Produced size is a bit too much (because of Kotlin/JS not being super optimized yet).

Vaadin has been around for a while now. I don't know how people feel about it. There is still some room for them on the market. It's "just" a backend service (Spring/VertX/etc) + a UI library (Vaadin's one/etc). It could look like Next.js but for JVM languages.

Just thinking out loud.

Vaadin Flow works great with Kotlin.

I've no interest in any Russian connected project including Kotlin, IntelliJ or nginx these days.
