About 115,118 websites in the PageSourceSearch index contain the code that reveals it; the 50 highest-ranked are listed below.
How is Discourse detected?
Discourse prints a meta generator tag reading Discourse followed by its version number. The discovery keyword is the exact bytes PageSourceSearch looks for in every stored page and script:

How does PageSourceSearch know a website uses Discourse?
By the source itself: Discourse prints a meta generator tag reading Discourse followed by its version number. 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 Discourse?
No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 115,118 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 Discourse 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 content="Discourse \d with wp-content/plugins/ lists the WordPress sites that use Discourse.
