Philosophy of Akka HTTP quoted from their documentations:

The Akka HTTP modules implement a full server and clientside HTTP stack on top of akka-actor and akka-stream. It’s not a web-framework but rather a more general toolkit for providing and consuming HTTP-based services. While interaction with a browser is of course also in scope it is not the primary focus of Akka HTTP.

Akka HTTP was designed specifically as “not-a-framework”, not because we don’t like frameworks, but for use cases where a framework is not the right choice. Akka HTTP is made for building integration layers based on HTTP and as such tries to “stay on the sidelines”. Therefore you normally don’t build your application “on top of” Akka HTTP, but you build your application on top of whatever makes sense and use Akka HTTP merely for the HTTP integration needs.
