Project List and Details

Couchbase Server and Client SDKs


This is the core server side of our distributed key-value/document database and its client SDKs.

Couchbase Server is built of a number of individual project subcomponents, each in their own git repository. We use the repo tool from the Android Open Source Project to manage them and how they should be built. A repo manifest file explains how the source code combines to become an individual release.

How to Contribute Code

Whether you have a fix for a typo in a component, a bugfix, or a new feature, we love to receive code from others!

It takes a lot of work to get from a potential new bug fix or feature idea to well-tested shipping code. Our engineers want to help you get there.


  1. Sign our Contributor License Agreement 1:
    1. Join our review site.
    2. Log into the review site.
    3. Fill out the agreement under  Settings > Agreements.
  2. Familiarize yourself with the build and test procedures for the code you’ll be working on.

    Some projects use a simple  GitHub pull request process. Other projects use a  code review process, where one of our engineers will look at your change and run tests to verify your fix.

    Each Couchbase open source project lists a primary technical contact, who can help with the technical aspects of getting a patch accepted.

  3. Reach out to the technical contact for that project and make sure you won’t be duplicating effort.

  1. Contributor License Agreements (CLAs) are common for projects under the Apache license, and typically serve to grant control of the code to a central entity. Because our code is available under the Apache License, signing the CLA doesn’t prevent you from using your code however you like, but it does give Couchbase the ability to defend the source legally and build and maintain a business around the technology.
