Realm SDKs¶

The MongoDB Realm SDKs are client libraries that allow you to connect to local and synced Realm databases, authenticate users, and interact with serverless MongoDB Realm applications. The SDKs include Realm Database, an alternative to SQLite and Core Data, so you can get started with just the SDK -- no additional dependencies required.

Get Started¶

Realm has native, idiomatic SDKs for most common application ecosystems and programming languages. Find yours below to start building your Realm app:
