KaTeX is a fast, dependency-free JavaScript library for rendering TeX/LaTeX math on the web. It renders synchronously with print-quality layout based on Knuth's TeX and supports both browser and server-side (Node.js) rendering to HTML strings.
Use cases
- render LaTeX math equations on a website
- display math formulas in a blog or documentation site
- server-side render math to HTML with Node.js
- fast synchronous math typesetting without page reflow
- render math in a React or static site
- typeset hundreds of math expressions on a page quickly
When to choose
- you need the fastest possible math rendering, especially with many expressions per page
- you want a self-contained library with no dependencies
- you need server-side rendering of math to plain HTML
- you want TeX-quality print layout
When to avoid
- you need full LaTeX support including all packages and environments
- you need MathML input or accessibility features beyond KaTeX's MathML output
- you need asynchronous rendering or MathJax's extension ecosystem
