Realm Kotlin

Fast, powerful data storage for Kotlin and KMM apps

Realm Kotlin makes persisting, querying, and syncing data as simple as working with objects in your data model, with idiomatic APIs that integrate directly with Coroutines and Flows.

Why use Realm Kotlin?


Fast, lightweight, and scalable

Realm’s integration with Flows automatically updates your views for you. The rich, expressive, and powerful query engine makes creating production-grade apps a breeze.


Save time with intuitive objects and KMM integration

No need for SQL, nor an ORM – working with your data is just like working with Kotlin-native objects. Realm is also compatible with Kotlin Multiplatform Mobile so you can build apps for mobile, web, desktop, and embedded devices from a single codebase.


Built-in mobile to cloud sync

Real-time mobile to cloud data sync makes it easy to build interactive features that keep data up-to-date across multiple devices, users, and the backend.
