Offline-first

Realm’s local database persists data on-disk, so apps work as well offline as they do online. And MongoDB Realm Sync automatically syncs that data with your backend whenever devices reconnect.

Realm’s object-oriented data model was built with simplicity in mind. No ORM or DAO required. And MongoDB Realm Sync saves you from writing thousands of lines of conflict resolution and networking code.
