PageSourceSearch

Websites by technology

Which websites use a given analytics tag, CMS, framework, chat widget or payment provider? Each page below lists the highest-ranked sites in the PageSourceSearch index whose HTML or JavaScript contains the exact code that reveals the technology, with the discovery keyword you can search, combine and filter yourself.

6,780 technologies have a page. The lists come from the source, not from a vendor's customer list: a site is included only when its stored pages or scripts contain the keyword. Counts are the index's estimates and refresh regularly.

How are these lists made?

PageSourceSearch stores the raw HTML and first-party JavaScript of each crawled site. For every technology a discovery keyword, the bytes that its tag, snippet or markup always leaves in a page, is searched byte for byte across the index; the sites whose source holds it, ranked by their position in the crawl's ranked domain list, make the page. Anything a technology leaves in the source can be searched the same way: try your own keyword, or read the query help.
