## Health v2 (maintenance only)
Score: 92/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 79, longevity 100
- inputs: {"age_days": 3844, "days_push": 7, "days_rel": 61, "gap_med": 69.0, "n_releases_24m": 5}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
MathJax is an open-source JavaScript display engine that renders LaTeX, MathML, and AsciiMath notation as high-quality typeset mathematics in all modern browsers, with SVG, CommonHTML, and other output formats. It includes built-in accessibility features such as screen-reader support, speech generation, expression exploration, and Braille output, and also runs server-side in Node.js.

## Use cases
- render latex equations in a web page
- display mathml in all browsers
- make math content accessible to screen readers
- convert tex or asciimath to svg in node
- add math typesetting to a documentation site
- render equations in an epub or lms
- typeset math in dynamically loaded content

## When to choose
- you need to display LaTeX, MathML, or AsciiMath in web pages without plugins or reader setup
- accessibility (screen readers, speech, Braille) is a requirement for your math content
- you need server-side math rendering or conversion in Node.js
- you want broad browser support and a flexible API for integration

## When to avoid
- you only need lightweight math rendering and prefer a smaller alternative like KaTeX
- you must support legacy browsers such as Internet Explorer
- you need print-quality PDF typesetting rather than web display

## Facets
- artifact type: library
- maturity: stable
- function: templating, ui-components, accessibility, graphics, parser
- domain: web-development, frontend, mathematics, education, accessibility
- platform: browser, cross-platform
- tags: math-rendering, latex, mathml, asciimath, svg-output, screen-reader-support, display-engine, typography, localization, nodejs, javascript
