Use the tool above to find out what CMS any website is using. Just plug in a URL and we will reply with the name of the CMS that website is using.
Note that not all sites use CMSs, so we might give you the name of the technology instead, or framework or any other bit of information we can find.
If you actually need to detect the specific themes used on a website such as Shopify, you can use our Shopify theme and app detector.
