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 four alternatives to MathJax, not only websites but also apps for Self-Hosted, Rust, 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, RaTeX and AsciiMath.
KaTeX is snappy, although not as many features are supported as in MathJax.
