Couchbase Lite is an ultra-lightweight, reliable, secure JSON database built for online/offline mobile application needs and is part of Couchbase's Mobile product.

As a lightweight, document-oriented NoSQL database engine, Couchbase Lite supports data synchronization and is suitable for embedding into mobile applications.

Lightweight means:

  • Embedded – the database engine is a library linked into the app, not a separate server process
  • Small code size – important for mobile apps because they’re often downloaded over cell networks
  • Quick startup time – important because mobile devices have relatively slow CPUs
  • Low memory usage – typical mobile data sets are relatively small, but some documents might have large multimedia attachments
  • Good performance – exact figures depend on your data and application

Document-oriented means:

  • Stores records in flexible JSON format instead of requiring predefined schemas or normalization
  • Documents can have arbitrary-sized binary data, such as multimedia content
  • Application data format can evolve over time without any need for explicit migrations
  • Language native query builder API provides fast lookups without needing special query languages

Syncable means:

  • Any two copies of a database can be brought into sync via an efficient, reliable, and proven replication algorithm
  • Sync can be on demand or continuous
  • Devices can sync with a subset of a large database on a remote server
  • The sync engine supports intermittent and unreliable network connections
  • Conflicts can be detected and resolved
  • Revision trees allow for complex replication topologies – including server-to-server (for multiple data centers) and peer-to-peer – without data loss or false conflicts

Couchbase Lite provides native APIs for:

  • Seamless iOS (Objective-C and Swift), Android (Java), and .NET development
  • Frameworks such as Xamarin
  • Embedded platforms
