Languages

Java SDK

The Java SDK forms the cornerstone of our JVM clients. It allows Java applications to access a Couchbase Server cluster. The Java SDK offers traditional synchronous APIs as well as scalable asynchronous APIs to maximize performance.

Scala SDK

Our new Scala SDK allows Scala applications to access a Couchbase Server cluster. It offers synchronous, asynchronous, and reactive APIs for flexibility and maximum performance.

C SDK

The Couchbase C SDK (libcouchbase) enables C and C++ programs to access a Couchbase Server cluster. The C SDK is also commonly used as a core dependency of SDKs written in other language to provide a common implementation and high performance. Libcouchbase also contains the cbc suite of command line tools.

Node.js SDK

The Node.js SDK allows you to connect to a Couchbase Server cluster from Node.js. The Node.js SDK is a native Node.js module using the very fast libcouchbase library to handle communicating with the cluster over the Couchbase binary protocol.

PHP SDK

The PHP SDK allows you to connect to a Couchbase Server cluster from PHP. The PHP SDK is a native PHP extension and uses the Couchbase high-performance C library libcouchbase to handle communicating to the cluster over Couchbase binary protocols.

Python SDK

The Python SDK allows Python applications to access a Couchbase Server cluster. The Python SDK offers a traditional synchronous API as well as integration with twisted, gevent, and asyncio. It depends on the C SDK (libcouchbase) and utilizes it for performance and reliability.

.NET SDK

The .NET SDK enables you to interact with a Couchbase Server cluster from the .NET Framework using any Common Language Runtime (CLR) language, including C#, F#, and VB.NET. It offers both a traditional synchronous API and an asynchronous API based on the Task-based Asynchronous Pattern (TAP).

Go SDK

The Couchbase Go SDK allows you to connect to a Couchbase Server cluster from Go. The Go SDK is a native Go library and uses the high-performance gocbcore to handle communicating to the cluster over Couchbase’s binary protocols.

Community Help

In addition to the Couchbase Support Team, help can be found from the community in our forums, and on our Gitter page.

Integrations

The Connectors pages show you how to integrate Couchbase Server with other data platforms, via Elasticsearch, Kafka connector, Spark connector, and ODBC and JDBC Drivers.

Tutorials

The developer bootstrap exercises and other tutorials highlight the use of Couchbase SDKs in the stacks you are most likely to use in development, such as Spring Data, Node Ottoman, and Python Flask.
