This repository contains compatibility data for Web technologies. Browser compatibility data describes which platforms (where "platforms" are usually, but not always, web browsers) support particular Web APIs.

This data can be used in documentation, to build compatibility tables listing browser support for APIs. For example: Browser support for WebExtension APIs.

• html/ contains data for HTML elements, attributes, and global attributes.

• http/ contains data for HTTP headers, statuses, and methods.

Projects using the data

Here are some projects using the data, as an npm module or directly:

• Add-ons Linter - the Add-ons Linter is used on addons.mozilla.org and the web-ext tool. It uses browser-compat-data to check that the Firefox version that the add-on lists support for does in fact support the APIs used by the add-on.
• Browser Compatibility Data Explorer - View, search, and visualize data from the compatibility dataset.
• caniuse - In addition to the existing caniuse database, caniuse includes features from the MDN BCD project, formatted and interactive like any other caniuse support table.
• Compat Report - Firefox Add-on that shows compatibility data for the current site in the developer tools.
• compat-tester - Scan local documents for compatibility issues.
• Visual Studio Code - Shows the compatibility information in the code completion popup.
• webhint.io - Hints to check if your CSS HTML and JavaScript have deprecated or not broadly supported features.
• WebStorm - JavaScript IDE allowing you to check whether all CSS properties you use are supported in the target browser version.
• Hexo Plugin: hexo-compat-report - Allows to embed MDN's compatibility table in a hexo blog post.
