Apache Pekko HTTP

The Pekko HTTP modules implement a full server- and client-side HTTP stack on top of pekko-actor and pekko-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 Pekko HTTP.

Pekko HTTP is a fork of Akka HTTP 10.2.x release, prior to the Akka project's adoption of the Business Source License.

Pekko HTTP follows a rather open design and many times offers several different API levels for “doing the same thing”. You get to pick the API level of abstraction that is most suitable for your application. This means that, if you have trouble achieving something using a high-level API, there's a good chance that you can get it done with a low-level API, which offers more flexibility but might require you to write more application code.
