Build better apps, faster.
Realm’s mobile database is an open source, developer-friendly alternative to CoreData and SQLite. Start in minutes, port your app in hours, and save yourself weeks of work.
Why Use Realm
Intuitive to Developers
Realm’s object-oriented data model is simple to learn, doesn’t need an ORM, and lets you write less code.
Designed for Offline Use
Realm’s local database persists data on-disk, so apps work as well offline as they do online.
Built for Mobile
Realm is fully-featured, lightweight, and efficiently uses memory, disk space, and battery life.
Object-Oriented:
Streamline Your Code
Realm was built for mobile developers, with simplicity in mind. The idiomatic, object-oriented data model can save you thousands of lines of code.
Live Objects:
Build Reactive Apps
Realm’s live objects mean data updated anywhere is automatically updated everywhere. If you need to freeze elements of your data for Reactive frameworks, you can do that, too.
