You can replicate local databases on-device — see: Intra-Device


You can sync with a centralized Couchbase Server database using Sync Gateway — see: Remote Sync Gateway

At the edge

You can sync directly with other edge devices, peer-to-peer, using a listener to interact with the Couchbase Lite replicator — see: Peer-to-Peer Sync
