[erlang-questions] CORS Supporting Erlang HTTP Server

They have different goals and states.

Cowboy is young and still sees fairly large changes (in part to 
accomodate to newer protocols like HTTP/2 or Websocket compression, and 
in part because there are still usability issues). However from version 
2 onward changes should be minimal for a while.

Cowboy aims to support the core protocols for Web development, and 
nothing more. This means HTTP 1 and 2, SPDY, Websocket, and so on. It 
also includes a REST machine (adapted from Webmachine). The main focus 
is on REST and Websocket first.

It does not include anything related to formats like JSON or HTML, 
enterprise protocols like RPC/SOAP/.. or anything related to XML, or 
Flash and so on.

There's a constant effort on keeping things small and tidy, and 
providing functionality that covers 99% of users. The changes are user 
driven, with unused features happily removed while new features get 
added after detecting patterns in the many user questions I receive (but 
only if they are in the scope, of course).

Hope that helps.
