Websites using KaTeX
KaTeX is a fast math typesetting library for the web.
About 4,085 websites in the PageSourceSearch index contain the code that reveals it; the 50 highest-ranked are listed below.
How is KaTeX detected?
KaTeX-rendered formulas include a span with the class katex-mathml, also when rendered at build time. The discovery keyword is the exact bytes PageSourceSearch looks for in every stored page and script:
katex-mathml Search the index for it
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 KaTeX

Questions about finding KaTeX
How does PageSourceSearch know a website uses KaTeX?
By the source itself: KaTeX-rendered formulas include a span with the class katex-mathml, also when rendered at build time. 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 KaTeX?
No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 4,085 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 KaTeX 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 katex-mathml with wp-content/plugins/ lists the WordPress sites that use KaTeX.
