It's also very simple to use and get started with. DOMPurify was [started in February 2014](https://github.com/cure53/DOMPurify/commit/a630922616927373485e0e787ab19e73e3691b2b) and, meanwhile, has reached version 2.3.6.

DOMPurify is written in JavaScript and works in all modern browsers (Safari (10+), Opera (15+), Internet Explorer (10+), Edge, Firefox and Chrome - as well as almost anything else using Blink or WebKit). It doesn't break on MSIE6 or other legacy browsers. It either uses [a fall-back](#what-about-older-browsers-like-msie8) or simply does nothing.
Our automated tests cover [19 different browsers](https://github.com/cure53/DOMPurify/blob/main/test/karma.custom-launchers.config.js#L5) right now, more to come. We also cover Node.js v14.15.1, v15.4.0, v16.13.0, v17.0.0, running DOMPurify on [jsdom](https://github.com/tmpvar/jsdom). Older Node.js versions are known to work as well.
