Ktor vs Akka HTTP: What are the differences?
Ktor: Framework for quickly creating connected applications in Kotlin. It is a framework for building asynchronous servers and clients in connected systems using the Kotlin programming language; Akka HTTP: HTTP client and server built on Akka actors and streams. The Akka HTTP modules implement a full server- and client-side 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.
Ktor and Akka HTTP can be primarily classified as "Microframeworks (Backend)" tools.
Ktor is an open source tool with 6.73K GitHub stars and 549 GitHub forks. Here's a link to Ktor's open source repository on GitHub.
