Concrete CMS, formerly concrete5, is an open-source PHP content management system with in-context editing.
About 2,464 websites in the PageSourceSearch index contain the code that reveals it; the 50 highest-ranked are listed below.
How is Concrete CMS detected?
Every Concrete page defines the CCM_DISPATCHER_FILENAME script variable in its head. The discovery keyword is the exact bytes PageSourceSearch looks for in every stored page and script:
A literal is matched byte for byte, case-sensitively. Combine it with another keyword, a domain, a kind or a date filter on the search page to narrow the list. About Concrete CMS

How does PageSourceSearch know a website uses Concrete CMS?
By the source itself: Every Concrete page defines the CCM_DISPATCHER_FILENAME script variable in its head. PageSourceSearch stores the raw HTML and first-party JavaScript of each crawled site and matches the keyword byte for byte, so every listed site's stored source contains it.
Is this a complete list of websites using Concrete CMS?
No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 2,464 websites that do; the count is the index's estimate at the time the list was computed. Run the keyword as a search to page through all of them, or add a kind or date filter.
How do I find websites that use Concrete CMS together with another technology?
Search for both keywords at once: several terms separated by spaces must all be found on the same site, or with the Same page toggle in the same page. For example CCM_DISPATCHER_FILENAME with wp-content/plugins/ lists the WordPress sites that use Concrete CMS.
