Enhance your applications with built-in key-value, MapReduce, full-text search and geospatial querying that go beyond simple bounding boxes. Stream the changes feed for seamless integration with event-driven applications and IBM Cloud Functions.

Durable replication

Learn about Cloudant replication

Move application data closer to the places it needs to be for uninterrupted data access, offline or online. Cloudant helps teams build progressive web apps, develop with an offline-first architecture or manipulate data on edge devices.

Cloudant on Transaction Engine instances have strong consistency and elimination of in-region conflicts. You can scale more for less, especially global querying, and storage is 4 times less. Data value encryption occurs within the database itself, with a per database encryption key. 


Mobile for Android and iOS

The Cloudant Sync library is used to store, index and query local JSON data on a mobile device. It is also used to synchronize data between many devices. Synchronization is controlled by your application. The library also provides helper methods for finding and resolving conflicts, both in the local device and the remote database.
