Features

KaTeX rendering of math claims to be:

• Fast: It renders its math synchronously and doesn't need to reflow the page.
• Print quality: Its layout is based on TeX.
• Self contained: It has no dependencies, so it can be easily bundled.
• Capable of server-side rendering: it has an option to generate HTML on the server (so, for example, one can pre-render expressions using Node.js and send them as plain HTML).

KaTeX implements a smaller subset of LaTeX's mathematical notation features than MathJax.^[2][5]
