Atlassian strongly believes in open source software. We support and contribute to the open source community in a number of ways — supplying our own code, supporting other projects by donating our software, and sponsoring Java User Groups.
Below are the most popular open-source instances using Atlassian software to better manage their projects and information about our popular Atlassian Plugin Framework that is used by thousands of developers worldwide.

Atlassian Plugin Framework
Atlassian's plugin framework allows developers to create plugins which extend the functionality of Atlassian applications such as JIRA and Confluence.
The plugin framework features a mature OSGi container that keeps plugins properly isolated from your application while allowing plugins to selective share services and code with each other.
Would you like to create plugins for your own web application? The Atlassian Plugin Framework is freely available to all who would like to turn their web application into a platform that can be extended at runtime.
