KaTeX vs MathJax Comments


- KaTeX is Free and Open Source
MathJax is described as 'Open source JavaScript display engine for mathematics that works in all modern browsers, using LaTeX math and MathML markup' and is an website in the development category. There are three alternatives to MathJax, not only websites but also apps for Self-Hosted, JavaScript and Node.JS. The best MathJax alternative is KaTeX, which is both free and Open Source. Other great sites and apps similar to MathJax are MathQuill and AsciiMath.
KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web.


Easily type math in your web app. Just load MathQuill and call the constructors on some HTML element DOM objects.

AsciiMath is an easy-to-write markup language for mathematics that includes a full fledged open-source JavaScript display engine for mathematics that works in all browsers.

AsciiMath uses its own markup language, and isn't a full LaTeX renderer on its own.


KaTeX is snappy, although not as many features are supported as in MathJax.
