We are an open co-operative of people, who are developing a free, open-source, and user-centric alternative to centralized group chat platforms, based on widely used protocols and standards. Learn more about our projects.

We also offer hosted services for a variety of applications on a not-for-profit basis. And we have recently created a community-led foundation for this purpose.

We collaborate on source code on GitHub as well as our own Gitea. For announcements and other news, you can follow us on the fediverse (recommended) or on Twitter.
