I am looking for compatibility data about browsers:

  • Does browser Firefox 32 support createDocumentFragment()?
  • Does browser Internet Explorer 5.5 support querySelectorAll()?
  • etc

Data should be easily downloadable under an open license, unlike quirksmode.
(for instance for use in an open source IDE or quality insurance tool)


The caniuse.com project includes compatabilities for many browsers versus CSS, HTML, JS API, SVG, and Other categories.

"Can I use" provides up-to-date browser support tables for support of front-end web technologies on desktop and mobile web browsers.

Raw data is on GitHub.
