I have installed SPDY Indicator chrome extension. It is detecting some sites as SPDY enabled and some as HTTP/2 enabled.

Which are the web servers that currently support HTTP/2? I know nginx support SPDY, but does it support HTTP/2? If it does, how can I enable it?

Update

Thanks to GolezTrol. The answer is no. Yes as of September 2015

Supported

  • IIS supports HTTP/2 in Windows 10[50]
  • OpenLiteSpeed 1.3.7 and 1.4.4 support HTTP/2 draft 16.[51]

SPDY, but no HTTP/2

The following list is out of date and it's probably not worth maintaining.

  • Nginx provides experimental support for SPDY (Draft 3.1) via a module[52]
  • Apache doesn't support SPDY in the current 2.4.x version, but mod_spdy allows adding it[53]
  • LiteSpeed Web Server currently supports SPDY/3.1[54]

Computer says "No" – Confraternity
This question and its answers is going to become out of date FAST!! Nginx does supports HTTP/2 now and has done for a couple of months. – Caraviello
The lists of supporting servers at github and Wikipedia will remain more up to date. – Caraviello
Em......i've just tested github and stackoverflow, it seems they haven't support HTTP/2 yet. Surprising !!! They should do as they are tech. focused website. :) – Undertone

There's a full list of web servers etc that support HTTP/2 at https://github.com/http2/http2-spec/wiki/Implementations

^ Not a full list. http/2 implementation != http2 web server. For example, caddyserver.com uses one of those implementations but is not its own implementation. (disclaimer: I'm the author of Caddy.) – Interesting

nginx released 1.9.5 mainline version last week. You have to compile nginx with --with-http_v2_module to enable HTTP/2 support. It does not support server push yet.

I wrote a simple post on how to set it up for local development on OS X with HTTP/2 in case it's of any interest for others: http://tech.finn.no/2015/09/25/setup-nginx-with-http2-for-local-development/
