WhatCMS.org looks at a variety of factors within a webpage to determine what CMS a website is using. We've developed algorithms for detecting all of the major CMS, but if you feel like we're missing one or if our algorithm is working well, let us know and we'll do our best to improve.
Keep in mind a website may use multiple CMS.Wordpress may be used as the primary CMS, while using vBulletin on a subdomain (forum.example.com) or subdirectory (example.com/forum). For this reason, you can enter any url in the form above to see what CMS is being used on a specific page.
