Create mobile apps that meet modern user expectations

Popular mobile apps have created higher user expectations. Mobile users demand reactive experiences, low latency, and instant data updates across platforms and devices. Sophisticated data and infrastructure layers make this possible, but they don’t have to be reinvented.

Delight users with data persistence

Storing data locally makes mobile experiences without interruption possible—even with network failures. Realm, by MongoDB, is an on-device database that minimizes device resource drainage. Object-oriented by design, Realm removes the need for an ORM or DAO, making development a breeze, and it’s seamlessly integrated with Atlas to enable always-on mobile experiences.

MongoDB is the best data platform for building mobile applications

MongoDB Atlas

Atlas is a developer data platform for building applications. At its core, it is on-demand, elastic, and fully managed MongoDB, with baked-in best practices, leaving developers free to build the next big thing.

Why MongoDB for your mobile apps?

Intuitive data model

MongoDB’s document data model & Realm’s object-oriented data model make it easy to work with native objects — no ORMs or DAOs needed.



Realm provides simple and secure SDK access from mobile apps directly to your data, whether in the backend or on-device.


Built-in sync

Atlas Device Sync automatically propagates changes in both directions between Realm, embedded in your mobile app, and Atlas in the cloud.



Index and query data any way you need. Device Sync exposes the data generated on mobile to Atlas services, allowing you to search, analyze, transform, combine, and visualize your app or user data with ease.


Data where you need it

Atlas lets you precisely control where your data lives so you can ensure fast performance anywhere and meet compliance requirements; Realm stores the data on your users' trusted devices.


Always on

Built-in redundancy and self-healing ensure service continuity of the cloud backend; users can also continue to use the app when offline, using data stored on device with Realm.



Fully managed MongoDB databases in Atlas auto-scale to meet growing data volumes and user loads; serverless Device Sync scales automatically and transparently, and you only pay for what you consume.


Run anywhere

Run the same data platform everywhere – inside any frontend device with SDKs for iOS, Android, React Native and more, on a single cloud, or even across multiple public clouds.
