Realtime syncing makes it easy for your users to access their data from any device, web or mobile, and it helps your users collaborate with one another.
Build serverless apps
Realtime Database ships with mobile and web SDKs so you can build apps without the need of servers. You can also execute backend code that responds to events triggered by your database using Cloud Functions for Firebase.
Optimized for offline use
When your users go offline, the Realtime Database SDKs use local cache on the device to serve and store changes. When the device comes online, the local data is automatically synchronized.
Strong user-based security
Realtime Database integrates with Firebase Authentication to provide simple and intuitive authentication for developers. You can use our declarative security model to allow access based on user identity or with pattern matching on your data.
Case Studies
Learn how Realtime Database helps teams across the world
STAGE uses Firebase and Flutter to cut release time in half
STAGE paired Flutter's front-end tools with Firebase's back-end services to build a multi-platform app. The app's infrastructure securely stores and delivers content to almost 2 million users in realtime for a smooth viewing experience, which helps them stand out in India's competitive streaming market.
Acintyo uses Firebase to streamline and speed up app development by 25%
With millions of users across 175 countries, the Galarm team used Firebase's fully-managed, scalable infrastructure to accelerate app development, automate tasks, and free up engineering time so they could focus on bringing their ideas to life.
