The library it replaced laid out mathematics in stages, and the answer was to render in one synchronous pass with no reflow at all. Speed was the motive, but the side effect is what makes the detection interesting, because a library for typesetting mathematics is closer to a statement of subject matter than to infrastructure. KaTeX is a JavaScript graphics from Khan Academy, first released in 2014, that renders TeX notation into HTML and CSS in the browser using JavaScript instead of leaving formulas to an image or a plugin. Nobody adds a math typesetter to a website by accident. The presence of KaTeX means somebody publishes equations often enough that formatting them by hand stopped being reasonable. As of October 2026 we detect KaTeX on 31,315 sites. United States accounts for 19,753 of them, with .com as the common suffix. Concentration of that kind reflects where technical documentation and courseware get published in English more than it reflects where mathematics is taught, and the country column should be read in that spirit. Who the population is matters more than how large it is. A domain that renders equations is a university department, a courseware or textbook publisher, a documentation site for a numerical library, a journal, a finance or engineering calculator, or a research blog kept by one person. Anyone selling into education technology, academic publishing, or research software is looking for precisely that set of domains, and a keyword crawl does not find it cleanly, because the mathematics on those pages exists as markup rather than as text a crawler can read. The limits are worth stating. Detection depends on the script or the stylesheet being loaded from a path we can recognise, so a copy renamed and self hosted inside a theme drops out. Version information is thin for this library, because the files are commonly served without a version anywhere in the path, which means the export cannot be filtered by release the way a dependency audit would want. A template that loads the renderer sitewide also registers on the whole domain even when a handful of pages carry an equation, so a row means a publisher who works with mathematical content rather than a page full of it. Used with that in mind, the download answers a question no per domain lookup reaches. Checking one address tells you a single institution renders formulas client side. The list tells you how many such publishers exist, which markets they sit in, and which suffixes they register under, which is the difference between a curiosity and an addressable population. ## Frequently asked questions How many websites use KaTeX? webatla detects KaTeX on 31K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking. Can I download the list of websites using KaTeX? Yes, as structured JSONL. Grab a free sample first. What's included for each site, and how fresh is it? Domain, DNS, RDAP/WHOIS, the full technology stack, IP & country, PageRank and Harmonic, re-detected and re-exported daily. How do I find the websites using KaTeX? Buy the technology dataset, then download the complete list of domains we detect using KaTeX, re-exported every day. What else is in the KaTeX technology data? Each row places KaTeX next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking. Can I download just the sites using KaTeX, or the whole database? Both. Every site running KaTeX comes in the Technologies dataset, one downloadable file. Or buy All data for the entire database: technologies plus identity, ranking, DNS and RDAP/WHOIS for every domain, combined in one file. Daily fresh export. How do I download the list of websites using KaTeX? Three steps: (1) grab the free 10,000-row sample to inspect the schema, (2) buy the Technologies dataset, (3) download the full list of every domain we detect running KaTeX as a JSON Lines file. It is re-exported daily, so you can re-download the freshest list any time inside your access window. Each row carries the domain plus DNS, WHOIS, IP, hosting country and rank. ## Get the full list of websites using KaTeX Pick the dataset that covers what you need.
