The web browser space is getting ready for its next big collaboration phase. Through its WebKit team, Apple is asking developers to pitch ideas for Interop 2027. This is the latest version of a yearly effort to make web technologies work well across different browsers. By pulling together feedback from the community, the group hopes to identify and fix the biggest pain points that hold back web development.
The Interop project began in 2022 to sort out common compatibility issues. It is a joint effort where the tech giant works alongside Google, as well as Microsoft and other major browser makers like Mozilla and Igalia. For the 2025 cycle, its shared test passes jumped from 29 percent to 97 percent over the year. Now, the focus is shifting to what needs fixing in 2027.
The submission process requires specific and testable standard features
The open call started on September 3 and will accept pitches until September 23. You can submit a proposal directly on GitHub. The WebKit team says that any submitted idea needs to focus on a specific, impactful, and valuable problem. It is much better to pitch a narrow fix, like a single font size adjustment, rather than a broad topic like typography.

The project relies heavily on automated testing to track progress. Because of this, developers need to link their proposals to stable web standards and existing test coverage. If an idea lacks mature testing infrastructure, you should pitch it as an Interop Investigation instead. The team also suggests searching GitHub first to support existing issues rather than making duplicate posts.
Developers must follow official guidelines to make a strong case
Putting together a good pitch means providing clear use cases and explaining how a change will help both users and developers. You should explain why your idea deserves priority over hundreds of other possible fixes. If you want to dive into the details, you can read the full guidelines on the WebKit blog.
Since the people reviewing these pitches might not know everything about last year’s ideas, you need to state your case clearly from the start. By taking part in this open call, everyday coders can help shape the future of web standards and build a better baseline for everyone.
