I’m so desperate for a fediverse calendar/event app that I don’t know if I can wait for someone else to get started. But I have no web development skills (or time). Someone please start a serious attempt with a patreon so I can feel useful
Some thoughts on existing services:
Upcoming.org: Not federated, “Upcoming wasn't built for event promoters, organizers, or venues” aka will never replace Facebook which is the goal
Friendica: A whole social network seems overkill. I don’t think they have full activitypub support yet.
https://gettogether.community this looks promising. They’re looking for contributors to help with ActivityPub support.
@michel Possibly try Osada and/or Hubzilla? I think they share much of the same codebase, but Osada gained ActivityPub support first. Is far as I know, none of the group and calendar features of either federate over AP though. (Last I tried, I've seen some incomplete AP federation features too, like direct messages showing up as public in Osada - no idea if that has been fixed.)
