@ajsadauskas @asklemmy I've been self-hosting and also use my instance for my private IT business. From what I can tell it's built on owncloud and the the server commands use the occ command that references that codebase.
Key apps to check out:
- Memories (for photos)
- Deck (for Kanban productivity boards)
- Mastodon Integration
- Polls (Doodle Alternative)
- Forms
-Appointments
- Talk (May need a high-end signaling server but can replace Google Meetup/Teams/Zoom/Slack)
