WPT

This page compares scores on the Web Platform Tests across web engines, using the latest master runs from wpt.fyi and Blitz's own test runner.

Score history

Percentage of subtests passing over time, one master run per day. Every engine's percentage is relative to the same denominator: the total number of subtests known to any engine in the latest runs (so lines are not distorted by tests being added to WPT, and an engine that skips tests is not flattered for it).
