I've been using https://ktor.io (by Jetbrains, same company behind Kotlin) but there are others like Micronaut and Quarkus. A few more options at: https://kotlinlang.org/lp/server-side/

As far as I'm aware there's no native server side framework available at the moment, but ktor could potentially support it in the future given the ktor client libraries work on native. You could also use GraalVM native image to build a JVM-free binary of your server, Quarkus has built-in support for it.
