Realm is a mobile database that runs directly inside phones, tablets or wearables.
- Mobile-first: Realm is the first database built from the ground up to run directly inside phones, tablets and wearables.
- Simple: Data is directly exposed as objects and queryable by code, removing the need for ORM's riddled with performance & maintenance issues.
- Modern: Realm supports relationships, generics, and vectorization.
- Fast: Realm is faster than even raw SQLite on common operations, while maintaining an extremely rich feature set.
