About Couchbase Server

Couchbase Server keeps records as JSON documents and pairs them with key-value access, caching that the database manages itself, specialized indexes and querying in a SQL-like language, all inside one distributed system. Couchbase, Inc. develops the product, and organizations can run it on their own infrastructure.

Enterprise and Community editions

The Enterprise Edition is sold under a commercial subscription license. The Community Edition is free for non-commercial or departmental use and is limited to clusters of up to five nodes. It does not include cross data center replication (XDCR). Teams that need to grow past five nodes or use the software commercially will need the Enterprise Edition. The Community license is a restricted license rather than an open source one.

Hosted service

Couchbase also offers Capella, a database-as-a-service, with tiers charged by the hour for each node. The service is an alternative to running the database on a company's own servers.

Release cadence

Version 8.0.3 is the newest release, dated September 2026, and the two before it arrived in June and March 2026, a pattern of roughly quarterly maintenance releases. Release notes sit in the vendor's documentation.
