It enables developers to build applications easier and faster with both the power of SQL and the flexibility of JSON.

Capella is Couchbase's DBaaS (Database-as-a-Service). It is fully managed, hosted, patched, and upgraded by Couchbase.

Developed as an alternative to traditionally inflexible SQL databases, the Couchbase NoSQL database is designed to help developers solve real-world problems and meet high scalability demands along with unparalleled performance.

  • Achieve fast, efficient bi-directional synchronization of data from the edge to the cloud and between clusters
  • Build seamless data sharing across users and devices – online and offline
  • Consistent programming model for building web and mobile apps

Couchbase is designed to help enterprise applications perform well (up to 10-20x faster than competition) while also scaling to match data volumes. The use of in-memory datasets allows you to process and optimize queries and indexing processes. Coupled with the features of Couchbase Mobile, applications can continue to operate even in offline mode.

Management Tools

  • Streamline configuration and setup, take advantage of multi-cloud agility
  • Built-in enterprise-grade security for the full stack
