Interop 2025 is a cross-browser effort to improve the interoperability of the web — to reach a state where each technology works exactly the same in every browser.

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.
