A Content Management System, or CMS, is a piece of software designed to help users create and edit a website. It's important to note, however, CMS do much more than help manage the text and image content displayed on webpages. They have evolved to help design the look of websites, track user sessions, handle searches, collect visitor comments, host forums and much much more.
Content Management Systems have been detected on over half of all websites with an even higher percentage detected on the most popular domains. If you ever wonder which CMS is behind a website you're looking at, just plug the url into the form above and we'll do our best to detect it for you.
WhatCMS.org looks at a variety of factors to determine which CMS a website is using. First, we fetch the webpage for the url in question then begin looking for indicators in the html markup and headers. Indicators range from the very obvious

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.
Dedicated Content Management System Detection
We have detection methods for 540 different content management systems and regularly update our algorithms.
All of our development efforts are used for expanding and improving our CMS detection capabilities. Nothing else.
Nothing is 100% accurate, but our detection service is as good as they come and we're always making improvements.
It's not uncommon to find more than one CMS per domain which is why users can check any url. e.g. example.com, foo.example.com or example.com/bar
Clear, uncluttered results and a free API make it easy to access our detection methods whether it's for an occasional lookup or integration into your own application.
