CMS Market Share

Wappalyzer, one of our other projects in cooperation with its original founder Elbert F, is a browser add-on that uncovers the technologies used on websites. It detects CMS and e-commerce systems, JavaScript frameworks, analytics tools and more.
We have compiled the global OpenSource CMS information provided by the browser add-on on this page to give you an idea of the Top 20 Open Source CMS tools out there and their current market share. There are currently over 20,000 people that have the add-on installed and are reporting this data. Keep in mind that the statistics are of course only a snapshot of the past 30 days and only cover roughly 1% of the entire web.

You can help Wappalyzer by downloading the browser add-on and start reporting CMS statistics, too.
