The web-platform-tests dashboard is a work-in-progress. The reported results do not necessarily reflect the true capabilities of each web browser, so they should not be used evaluate or compare feature support. Each browser listed here is currently tested at its latest stable release.
The WPT Dashboard, wpt.fyi, displays results for the web-platform-tests, or WPT, which are a group of test suites for many web platform specifications.
If the web platform as a whole were an engineering project, it'd be crazy not to have a test suite that's run regularly. The goal of the WPT Dashboard is to promote viewing the web platform as one entity and to make identifying and fixing interoperability issues as easy as possible.
The WPT Dashboard project is comprised of two parts:
Running: currently the goal is to run WPT in Chrome, Edge, Firefox, and Safari daily.
Serving: this site, wpt.fyi, displaying test results.
Source and Documentation
The source code for both running and serving test results is on GitHub.
