Firebase Realtime Database
Store and sync
data in real time
Real time syncing for JSON data
The Firebase Realtime Database is a cloud-hosted NoSQL database that lets you store and sync data between your users in realtime.
NEW: Cloud Firestore enables you to store, sync and query app data at global scale.
Collaborate across devices with ease
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
The 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.
