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. Available for Swift, Objective-C, Java, Kotlin, C#, and JavaScript. Realm’s object-oriented data model is simple to learn, doesn’t need an ORM, and lets you write less code. Realm’s local database persists data on-disk, so apps work as well offline as they do online. Realm is fully-featured, lightweight, and efficiently uses memory, disk space, and battery life. Realm was built for mobile developers, with simplicity in mind. The idiomatic, object-oriented data model can save you thousands of lines of code. 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.
Features
- Realm is the first database built from the ground up to run directly inside phones, tablets and wearables
- Data is directly exposed as objects and queryable by code, removing the need for ORM's riddled with performance & maintenance issues
- Most of our users pick it up intuitively, getting simple apps up & running in minutes
- Realm supports relationships, generics, vectorization and Swift
