Yo, listen up, y’all. The Interop 2026 call for proposals is now open, and it’s time to unleash your inner web developer and submit your ideas! 🚀
Yo, we’re so proud to have been a part of the Interop project for the past 5 years, and it’s a real honor to see the passion and dedication of our industry for pushing the limits of what’s possible for developers to do on the web. And let me tell you, the collective enthusiasm is off the charts.
Like a boss, grid, subgrid, flexbox, container queries, popover, the `:has()` selector, and declarative shadow DOM are just not in their current state without the Interop project. Think about it: without these critical building blocks, developers would struggle to create seamless and performant web experiences, especially on devices with limited hardware support.
This year, View Transitions, URLPattern, and the `@scope` rule are on track to become interoperable across the web, making it possible for web developers to truly rely on these features in a simple and intuitive way. This is a major step forward for the web, and it’s important to ensure that these new standards-based capabilities are widely adopted and supportedThe Interop 2026 call for proposals is now open, submit your ideas now!
We’re very proud to have been part of the Interop project for the past 5 years, and it’s amazing to see the collective enthusiasm of our industry for pushing the limits of what’s possible for developers to do on the web.
Critical building blocks like grid, subgrid, flexbox, container queries, popover, the :has() selector, and declarative shadow DOM would just not be in their current state today if it wasn’t for the Interop project. In fact, just this year, View Transitions, URLPattern, and the @scope rule are on track to becoming interoperable across the web, making it possible for web developers to truly rely on these features in a simple and performant way.
Interoperability is essential for ensuring the web remains a unified platform where developers can build great products and users have the freedom to achieve their goals using the browser of their choice.
But interoperability is never done. The web needs to constantly evolve to meet the needs of its users and the devices they use. We need to continue adding new standards-based capabilities to the web all the time, and ensure they’re interoperable quickly, down to the tiniest details.
That’s why the Interop project has been running for the past 5 years, and that’s why we’re already planning for the next iteration of the project.
Starting today, you can now send your ideas for Interop 2026! Help us choose which web platform features to improve next year by sharing what matters most to you.
Review the submission guidelines and submit your proposal now. The submission period will remain open through September 24, 2025.
You can also take a look at the selection process to understand how and when we’ll review the proposals, and what the next steps are.
