Version 3.1 simplifies apps and makes them more secure, scalable, and efficient

Develop faster using off-the-shelf sync with built-in authentication and conflict resolution

Cloud-to-edge sync

Securely sync mobile apps from cloud to edge. Couchbase provides security of data between your web, mobile, and IoT apps running Couchbase Lite and your backend Couchbase Server, as well as between cloud and edge data centers, including Couchbase Capella.

Built-in data integration APIs

Use secure RESTful APIs for accessing and managing data over the web and webhooks to integrate with external web clients, data stores, and services.

Robust security

Enforce read and write access from the Scopes and Collections level down to individual user and role. Admin REST API enforces authentication and role-based access control by default. Take advantage of third-party Open ID Connect providers or bring in custom providers.

Elastically scalable in real time

Vertically and horizontally scale Sync Gateway nodes to handle changes in capacity demands. Apply tunable read and write scaling options to meet performance demands.
