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.

JIRA Studio

Our hosted development suite, JIRA Studio is available for qualified open source projects. JIRA Studio combines JIRA, Confluence, Subersion, FishEye and Crucible in a single, integrated, hosted suite.

Please note that due to inherent hosting costs, JIRA Studio applicants are evaluated against a greater set of criteria, including existing project viability, velocity and approvals may take up to two weeks.
