httpstatus.es is an easy to use http status code reference site. An individual code can be accessed via httpstatus.es/{status_code}.

Each individual code is stored in a file specific to the class it is a part of. For example 404 is stored in 4.json, along with all other 4xx codes.

I have yet to decide on the criteria that a status code must meet to be included. I am unsure if including vendor specific status codes is sensible (eg: Twitter and Facebook API have their own status codes) or if it's confusing. For now I will accept any that have some form of notability, long term I would like to have a toggle for whether to show "real" only, or to include "vendor specific".

If you have any feedback please supply it via the github issue system.

(note: I am not 100% happy with the current code store format ({class}.json) however I've been unable to formulate a better idea that allows for the class information (summary) to be stored with the codes. I am open to suggestions, but it must remain a flat file solution to allow new codes and changes to the codes via git)

json format

{
   "class":{
      "title":"1xx Informational"
   },
   "codes":{
      "100":{
         "title":"Continue",
         "summary":"Client should continue with request",
         "descriptions":{
            "wiki":{
               "body":"Wikipedia description",
               "link":"http:\/\/en.wikipedia.org\/wiki\/List_of_HTTP_status_codes#100"
            },
            "ietf":{
               "body":"IETF Description",
               "link":"http:\/\/www.ietf.org\/rfc\/rfc2616.txt"
            }
         }
      }
   }
}

notes

httpstatus.es is built with klein.php and designed by myself. This is my first attempt at open sourcing anything that I have made.
