Play v2.6.x now supports HTTP/2 (however, still not production ready yet): playframework.com/documentation/2.6.x/Highlights26 – Dymoke

Answer 1

Things have changed since this was first answered and we've worked on implementing HTTP/2 in Akka HTTP since. Akka HTTP has become the default backend for Play in 2.6 so now it can be used.

Documentation: https://www.playframework.com/documentation/2.6.x/AkkaHttpServer#HTTP/2-support-(experimental)

Please note that as of writing this comment (early July 2017) support for HTTP/2 is still experimental, which means there's a few missing bits we know we need to implement (and are going to in the coming weeks; In the meantime, feedback from the community trying it out in the real world would be very valuable, thanks!)

Hi @Konrad, would you have an estimation when does the production-ready (i.e., non-experimental) HTTP2 support will be available? – Heartbreaking

Answer 2

No, Play 2 does not yet support HTTP/2. Play uses akka, which does not have HTTP/2 support yet. See this bug: https://github.com/akka/akka/issues/16862

Still not supported as of today, but it seems to be on the way : github.com/playframework/playframework/issues/5817 – Harman

That is not correct, Play uses Netty. I'm not sure how this is an accepted answer. playframework.com/documentation/2.5.x/… – Caramelize

It's a good answer -- the plan is to provide HTTP/2 through the akka-http engine, and it's still in progress. – Schrick

Note that Akka's HTTP/2 support in Play has landed in 2.6 as an experimental feature, try it here playframework.com/documentation/2.6.x/AkkaHttpServer#HTTP/… – Insipid
