How can I tell is someone's website is a CMS?

October 22, 2012 / Updated: October 22, 2012 / Lena Shore


How can I tell if a site has a CMS (Content Managed Site) installed? I have a client that has a site and wants me to add a page to it. I have the login info, but I can’t tell if they use a CMS for changes. It doesn’t look like it is, but how can I be sure?


You can’t always tell, because there are a lot of different CMSs. And, where many of them have specific default installations, it doesn’t mean they can’t be changed.

Here are some hints.

  • Look at the source code for words like drupal, wp-content in the metatags.

WordPress Sites: Try the links below. If you get a login, you have a winner. If you get a 404 error, you don’t:

  • or
  • or






  • or
  • or



Finally, here is a neat little tool that will run some tests to see if it can identify a website’s framework.

    Actually you can tell, if you download Mozilla Firefox and download an add-on called Wappalyzer it will display in the browser an icon of the CMS system that the website is using when you visit the website.

    That way you don’t have to go to each of those links as mentioned above. I can easily tell that this is a WP website just by looking at my wappalyzer bar.

    Heres the link –

    Hope this helps,

      Jake – what a cool little tool!! Thank you! I assume that the favicon is overridden if there is a different one existing?
