About the web features explorer website

The goal of the Web platform features explorer website is to visualize the data that's in the web-features and web-features-mappings repositories.

This is a project from the W3C WebDX Community Group (WebDX CG). The source code is available on the web-features-explorer GitHub repo.

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