A three-level layer cake, consisting of the following layers: a top, translucent layer labelled “Realm Mobile Database,” a middle, transparent layer labelled “Realm Sync,” and a bottom, bright green layer labelled “Atlas,” with smaller boxes arrayed around it, labelled “Functions,” “Triggers,” “GraphQL,” and “Data Access Controls.”
MongoDB Realm’s Application Services reduce the amount of code required — freeing up teams to dream up new ideas and build great features. Realm provides a fully managed, serverless back end and manages the flow of data between MongoDB Atlas and client devices.

The simplest way to stand up your app

Outsource the complexity of back-end creation, configuration, and operations to MongoDB Realm. Save yourself hours of coding and troubleshooting infrastructure — and spend more time building the applications of tomorrow.

Fully serverless — to scale with confidence

Built on a serverless architecture, MongoDB Realm scales seamlessly to keep up with your user growth. No need to provision servers, manually configure and maintain infrastructure, or worry about mismatched resources causing latency or outages.

Implement dynamic application logic

Execute custom database logic with a wide variety of preset services, including triggers, functions, and GraphQL. Create dynamic applications that can respond to events (like signups or database changes) in real time.

Fully managed, fully secure APIs

Lean on production-ready APIs — removing countless weeks of work and hours of coding. Our APIs and HTTPS Endpoints automatically connect data wherever you need it to go — and can be used alongside other services to secure data access for any service or back end.
