Welcome to the Atlas Device SDK Docs
Atlas Device SDK is a suite of app development tools optimized for data access and persistence on mobile devices. Use the SDKs to build data-driven mobile, web, desktop, and IoT apps.
The SDKs provide tools to read and write Atlas data from devices. Your app can sync automatically with MongoDB Atlas and other devices using Device Sync. You can call Atlas Functions from a device. The device persistence layer is Realm, an embedded, object-oriented database that lets you build real-time, offline-first applications.
We provide SDKs for most popular languages, frameworks, and platforms. Each SDK is language-idiomatic and includes:
The core database APIs for creating and working with on-device databases.
The APIs you need for connecting to the App Services backend so you can make use of server-side features like Device Sync, Authentication, Functions, Triggers, and more.
