About this website

The Web platform features explorer website is a project from the W3C WebDX Community Group (WebDX CG). Its goal is to visualize the data that's in the web-features and web-features-mappings repositories, which the WebDX CG maintains.

This means that, on this website, you will find information about web features such as their names, descriptions, which browsers they're supported on, Baseline statuses, links to MDN documentation, specifications, vendor positions, vendor bugs, web platform tests, user surveys, browser usage counters, and more.

To learn more about Baseline, see What is Baseline?.

The website's content was last generated on 10/9/2025 using web-features 3.4.0-dev-20251008182201-e947bff and browser-compat-data 7.1.11. The source code of the website is at web-features-explorer GitHub repo.
