KaTeX is a fast, dependency‑free JavaScript library that renders LaTeX math expressions as high‑quality HTML/CSS. It works in browsers and on the server via Node.js or Deno.
Use cases
- render LaTeX equations in a web page without loading MathJax
- pre‑render mathematical formulas on the server for static site generation
- display interactive math content in a React or Vue component
- convert LaTeX strings to HTML for email newsletters
- embed math in markdown editors with live preview
When to choose
- you need sub‑millisecond rendering of math on the client
- you want a library with zero runtime dependencies
- you require server‑side rendering of equations for SEO
- your project targets browsers that support modern JavaScript
When to avoid
- you need full MathML support or advanced LaTeX packages not implemented in KaTeX
- you rely on automatic equation numbering and cross‑references that KaTeX does not provide
- you prefer a heavyweight solution with extensive extensions like MathJax
