Calling for Interop 2027 proposals
Summary
Microsoft Edge announces the Interop 2027 call for proposals, inviting developers to submit ideas for improving cross‑browser consistency on web platform features. Strong proposals should address real developer pain, have measurable impact, and be backed by tests or clear test plans.
- Interop 2027 proposal window is open now until 23 Sep 2026; selections announced early Feb 2027.
- Proposals should target standards‑based features with concrete developer impact and measurable test coverage (WPT).
- Evidence of ecosystem impact (frameworks, issue trackers, real‑world sites) strengthens a submission.
- The Interop team tracks unmet needs on a public “Top Developer Needs” dashboard to guide future work.
Cross‑browser inconsistencies cost developers time and introduce bugs; coordinated Interop work helps surface and fix these gaps, making new web standards more reliable for production use.
