A modern programming language that makes developers happier.

kotlinlang

Tried ktor, wasabi and even nanohttp but no luck

All those web servers are JVM based, for native you need native http server library

Take a look on this sample that uses microhttpd C library:
<https://github.com/JetBrains/kotlinconf-spinner/tree/master/kotlin-native/samples/fullstack/httpserver>

There are plans to make ktor multuplatform and some parts already there, but not ready yet

also wasabi is deprecated (“merged to ktor”)
