@Daojoan yuck, that sounds gross. We've got Matrix -> Forgejo (or Gitlab), with notes in QOwnNotes, projects in WeKan or NextCloud deck, with meetings in BigBlueButton or Jitsi (via Matrix)... All of it is 100% #Libre/#FOSS, we host it all ourselves, and it all costs us nothing except a bit of my time. Plus we control all the data. I think there might be an opportunity here. Single sign-on is via Authentik. See https://tech.oeru.org/updating-oer-foundation-web-services-february-2023 for a full list of the services we use (+ howtos)...
