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). https://compose-web.ui.pages.jetbrains.team https://compose-web.ui.pages.jetbrains.team 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.
