Getting started

Welcome to the Atlassian Developer Documentation. Using the Atlassian plugin software developer kit (SDK), you can create apps to extend Atlassian Data Center products: Jira Software, Jira Service Management, Confluence, Bitbucket, and Bamboo.

We also offer a number of infrastructure tools to help you create, market and sell your apps. For example, thousands of customers visit the Atlassian Marketplace and the Atlassian Marketplace in-product every day, to find apps they may want to install.

If you meant to write an app for an Atlassian Cloud product then please see the following guides instead:
