Site update: web-features now included + new feature list functionality

2025年10月11日T12:30:39+00:00

Today's site update adds a number of new features:

Web-features browser support tables

In addition to the existing caniuse and MDN BCD support tables, features from the web-features project will now appear in search results and elsewhere on the site.

Each web-feature table includes the support included from the major browsers tracked as well as derived support for other browsers where available. Each table also includes a link to the list of all BCD sub-features that the feature's support is based on. Web-features that have a caniuse equivalent are currently hidden to prevent duplicate information (similar to how BCD features are handled).

Note that currently there are still a few places where only the original caniuse features are listed or considered (for example the comparison tool), these will be updated to include web-features in the future.

New feature list UI and improved filtering/sorting

Any search or filter result now allows the results to appear in a simplified list instead of just the support table view. These entries will include Baseline status (when available) as well as the global usage % range.

Lists of features can be be grouped by category, spec status and Baseline status and sorted by name, support level or Baseline date (see example). Filtering can be accomplished via the filter button at the top right side of the feature list.

This update includes a number of backend changes and various other fixes as well. If you run into any bugs please report them at the caniuse data issue tracker.
