Offline & sync
EntityFlow saves your edits locally in the browser as you work, so a dropped connection never stops you. You can keep adding tables, editing columns, and drawing relationships with no network at all.
When you lose your connection, a banner appears:
Offline — your changes are saved locally and will sync when you reconnect.
Reconnecting
As soon as you're back online, your offline edits reconcile with everyone else's automatically. Because the underlying model is a conflict-free CRDT, there's nothing to resolve by hand — your changes and your collaborators' changes merge cleanly and every client converges to the same diagram.
Per-user undo
Undo is per-user. Pressing undo only rolls back your own changes — it never touches a collaborator's work. This means you can freely undo a mistake during a busy multiplayer session without worrying about clobbering someone else's edits.
Offline editing keeps your work safe on a single device. To collaborate live again, reconnect to the server — see Real-time collaboration for the connection states (Offline / Connecting / Live).
