WinterCG

Web-interoperable Runtimes Community Group

This community group aims to provide a space for JavaScript runtimes to collaborate on API interoperability. We focus on documenting and improving interoperability of web platform APIs across runtimes (especially non-browser ones). This is done through discussions among runtimes, proposals in specification venues (WHATWG, W3C) for new web APIs and for changes to current web APIs, and documentation of existing runtime behaviours.
