Specific characteristics

Now a part of MongoDB Data Platform, Realm Database is the fast, easy to use, and open source alternative to SQLite and Core Data. Used by over 100k+ developers and downloaded over 2 billion times, Realm powers the world’s most innovative products and services.

Built for use on mobile devices, Realm solves for the common challenges of mobile development that are caused by inconsistent network connectivity, device constraints, and the need to build apps that provide a consistent experience across multiple platforms.

By embedding a full-featured database directly on the users’ device, Realm makes data access fast and efficient, regardless of the amount of data or quality of connection. Apps built on Realm are ACID compliant, function even when offline, and enable a seamless cross-platform experience. With support for complex queries, safe threading, encryption, and a reactive architecture to create responsive and fluent UIs, Realm allows developers to simply their code and focus on building powerful and engaging cross-platform experiences.

Competitive advantages

Realm ensures offline-first functionality, meaning apps run smoothly and deliver a best-in-class experience even when users lack a strong connection. Even complex queries complete in nano-seconds, making Realm faster than alternative mobile databases. And Realm eliminates the need to maintain an ORM by using objects to store data, meaning it is fast for developers to learn, easy to use, and simplifies data persistence for mobile devices.

Typical application scenarios
  • Mobile Consumer Apps

  • First-Line Worker Apps

Key customers
  • Cathay Pacific

  • Royal Carribbean Cruise Lines

  • Open Source Database powers apps built by Google, Netflix, Amazon, Dropbox, Intuit, SAP, Hilton, McDonald’s and more.

Market metrics
