Interop 2025: another year of web platform improvements

Published: February 13, 2025

After the huge success of Interop 2024, the project returns today with a new set of focus areas for 2025. While we couldn't include every suggestion made this year, the final list reaches across the web platform—from CSS to performance-related features.

The focus areas for 2025

  • Anchor positioning
  • backdrop-filter
  • Core Web Vitals
  • <details> element
  • Layout
  • Modules
  • Navigation API
  • Pointer and mouse events
  • Remove mutation events
  • @scope
  • scrollend event
  • Storage Access API
  • text-decoration
  • URLPattern
  • View Transition API
  • WebAssembly
  • Web compat
  • WebRTC
  • Writing modes

In addition, and as in previous years, there's a set of areas for investigation. These are areas where we don't have enough information or tests to include as a focus area, but the group feels some work should be done to get them to a stage where we can include them.

  • Accessibility testing
  • Gamepad API testing
  • Mobile testing
  • Privacy testing
  • WebVTT

We're excited about all of these features and the improvements this year's project will bring to the platform. And, as with last year, the project will make a whole set of things Baseline Newly available. This post shares more information about some of the features on the list, with links to information to find out more.

You can follow along on the Interop 2025 dashboard at wpt.fyi/interop-2025 and as things become Baseline Newly available they'll show up in the Baseline 2025 list on webstatus.dev too.
