Welcome to the Atlassian Developer Documentation. Using the Atlassian plugin software developer kit (SDK), you can create add-ons to extend Atlassian applications like JIRA, Confluence, Bitbucket Server, and Bamboo.
We also offer a number of infrastructure tools to help you create, market and sell your plugins. For example, thousands of customers visit the Atlassian Marketplace and the Atlassian Marketplace in-product every day, to find plugins they may want to install.
Building for Atlassian Cloud?
You'll use the Atlassian Connect framework to build for instances hosted in the cloud on Atlassian's servers. You'll still need to install the SDK for your local development.
