Atlassian – Open Source

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.

Our developers write a lot of open source code both in their free time and on company time. It helps to keep skills up-to-date, all the while contributing back to the community.
