Couchbase Lite

Embedded NoSQL client database with full CRUD, search, peer-to-peer data sync, and SQL query capabilities that runs locally on edge devices such as mobile, desktop, IoT, and custom embedded devices. Built from the ground up for embedded data storage and processing, Couchbase Lite natively supports all major operating systems and platforms.

Cloud sync

Couchbase Mobile includes a secure gateway for data synchronization over the web, with support for authentication, authorization, and fine-grained access control. Choose from fully managed sync with Capella App Services, or install and manage Couchbase Sync Gateway yourself.
