  • I tried it then ended up wrapping Vert.x with ZIO instead which is now open source. Is super-fast, lightweight and minimal.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • Http4s

    A minimal, idiomatic Scala interface for HTTP

  • In reality, your performance issues will not be http4s, but something else. That being said, there are improvements that http4s can and is making, and I'm quite excited about the future 1.0 release, which has some important and fundamental performance improvements already, like a a 125% performance improvement on the plaintext benchmark from https://github.com/http4s/http4s/pull/6091 - and finally, yes, akka-http does have very good performance, but you can also get good performance out of http4s.

  • rho

  • Rho was abandoned for some time, but right now it is receiving updates and I believe we can expect the release pretty soon.

  • To add to this, there's also different levels of JVM tuning between akka-http and http4s: https://github.com/TechEmpower/FrameworkBenchmarks/issues/3442

  • Akka HTTP

    The Streaming-first HTTP server/module of Akka
