We are building the data layer for the mobile internet

Our mission

At Realm, our mission is to help developers BUILD BETTER APPS FASTER™. We provide a unique set of tools and platform technologies designed to make it easy for developers to build apps with sophisticated, powerful features — things like realtime collaboration, augmented reality, live data synchronization, offline experiences, messaging, and more.

Today we are focused on mobile computing, but our vision is much larger. Everything we build is developed with an eye toward enabling developers for what we believe the mobile internet evolves into — an open network of billions of users and trillions of devices, and realtime interactivity across them all.

What we do

The core of our product line is the Realm Database. A true object database, it transforms how developers work live objects update automatically, run code in response to changes, and persist easily. It fully replaces the old-fashioned SQLite-based databases that are the alternatives for iOS and Android developers today.

Our flagship product, the Realm Platform, extends that core with realtime data synchronization and event handling on the server side, all seamlessly connected to the apps. Developers use the platform to build apps with powerful functionality like messaging, collaboration, and offline-first capabilities. The platform is also ideal for mobilizing existing APIs, making it easy to build highly responsive and engaging apps connected to legacy systems and services.

We’re proud to provide the Realm Database entirely free and open source. We are also proud to be the creators and maintainers of popular developer utilities and open-source projects including SwiftLint and Jazzy. And we are committed to producing and publishing the very best developer content, as well as supporting great developer events and meetups around the world.

Where we’re going

We’re building a data layer that can deliver the full potential of the mobile internet. We believe it can enable more powerful apps and more engaging experiences, on more devices. A mobile-first world is just beginning, and we’re working on it every day.
