WPE Web Support Status

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 a score drop over time is observed, then the most likely cause is either flaky tests that fail intermittently, or the addition of new tests in WPT, often reflecting new specification features, rather than a removal of capabilities from WPE WebKit.

For an alternative view that includes a more detailed list of supported Web APIs, JavaScript features and CSS properties, check the BCD test results.

• These results were obtained using a WPE build with experimental features enabled. Because feature availability can vary by build configuration, certain features shown here may not be present in other WPE builds.
• 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

This data is automatically obtained by running mdn-bcd-collector tests with WPE. It presents Browser Compatibility Data (BCD) for different WPE versions, covering Web technologies, such as Web APIs, JavaScript features, CSS properties and more.

The list below shows features available in the selected WPE version. It indicates only the presence of each feature, not the level of support. For an alternative view that includes specifications and support scores, refer to the WPT test results.
