Why Use MongoDB Realm

Automatic Conflict Resolution

All data changes are stored in a unified history and automatically merged via timestamps and operational transform. Data is always eventually consistent, and app reliability is guaranteed.

Cross-platform Solution

MongoDB Realm makes it simple to build a consistent app experience for your users, whatever their platform – iOS or Android, .NET, React Native, or Node.js.

Offline-first development

Realm’s local database is intuitive to use, lightweight, and fully featured. It persists data on-disk, and can sync data with Atlas whenever devices are connected.

Scales with you

With a backend powered by Atlas, apps built with MongoDB Realm easily scale up or down infrastructure. Use only the resources you need, and pay only for what you use.

Fully encrypted and secure

MongoDB Realm lets you encrypt data in-flight or at-rest, both in the cloud and on-device. See our Trust Center for more security information.

Pricing

MongoDB Realm calculates usage based on the data you sync and the requests your application makes. You’ll only pay for what you need.
