Nextcloud is fedi-enabled, with its Activities stream using ActivityPub since the standard was created, and more recently the Nextcloud Social app which is lately getting developer attention again.

Of course Nextcloud is decentralized in its entire setup, with its federation features allowing cross-server collaboration using the OpenCloudMesh protocol (in standardization at IETF).

I'll give a bit of an overview of where we are and talk about building apps with Nextcloud. I'm replacing a far more technical person who I had hoped could do this talk, so please be gentle with the deep code questions! Though I'm sure there will be somebody in the audience who actually knows the answers... I'm usually lucky that way.
