Explanation

This data is automatically obtained by running Web Platform Tests (WPT) with WPE. It shows all Web specifications supported or partially supported by WPE (≥30% WPT pass rate).

The numbers given below are necessarily a crude measure of support: it's possible to have what looks like a poor score while supporting the main body of a specification and missing a number of tiny edge cases, for example. That said, in general, a specification with a score above 70% can be considered supported; any score between 30% and 70% can be considered partially supported; and any score below 30% indicates limited or almost no support.

If you see a score drop over time, remember that this is most likely because flaky tests that fail intermitently or because the addition of new tests in WPT, possibly due to new specification features, and not the removal of capabilities from WPE WebKit.

Notes:

Detailed results of the automated WPT tests for WPE are available at wpt.fyi
JavaScript specifications are barely covered here. To explore those, see the results for JavaScriptCore at test262.fyi
