SDKs for Couchbase Operational Database

A fast and scalable database is even better when it’s easy to develop for. Couchbase gives you the SDK APIs to work with Capella, our managed solution, or self-managed options in your private Cloud or datacenter.

val json = JsonObject("foo" -> "bar", "baz" -> "qux")

collection.reactive.upsert("document-key", json)
    .doOnError(err  => println(s"Error during upsert: ${err}"))
    .doOnNext(_     => println("Success"))
    .subscribe()

Couchbase is a large platform — covering many services — and Couchbase SDKs are not thin wrappers generated around a REST API, but well thought out interfaces to the platform that make it easier to design and maintain your client code, and work with Couchbase in more natural ways for your platform.

The links above will take you to the latest version of your chosen SDK. Should you need to look up something for an older release, you’ll discover there a dropdown version selector (in the left-hand navigation) for each SDK release — and links to docs for older, unsupported versions in the docs archive.

Couchbase C SDK - libcouchbase (lcb) - is also available, and supported, but is no longer actively added to with new Server features.

For new projects, choose instead the C++ SDK — or possibly Go or Rust — for a modern, fully-featured SDK, with excellent performance.


Alternatives to SDKs

The Data API gives access to data in Capella Operational clusters — for when to use the Data API, or Capella’s other REST APIs, see Data API vs. Couchbase SDKs.


The Bigger Picture

SDKs are also available for our real-time analytics service, Operational Insights — see the Operational Insights SDKs pages:
