Call for Participation in Web-interoperable Runtimes Community Group

The Web-interoperable Runtimes Community Group has been launched:

The Web-interoperable Runtimes Community Group (wintercg) is intended to augment the work of other existing community and working groups focusing on the development of Web Platform features and APIs by focusing directly on the specific needs of non-Web Browser based implementations. Whereas existing community groups such as the Web Incubator Community Group (WICG) and the Web Hypertext Application Technology Working Group (WHATWG) are each explicitly scoped to features “that would be implemented in a browser or similar user agent”, it will be the goal of the wintercg to focus on implementation of those same features in environments such as backend servers, serverless compute, IoT, command-line tools, and so forth — essentially, everything that is not a browser.

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2022-04-22 by James Snell. The following people supported its creation: James Snell, Luca Casonato, Romulo Cintra, Benjamin Gruenbaum, Tobias Nie├čen. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at

Thank you,
W3C Community Development Team
