Jira is used by a large number of clients and users globally for project, time, requirements, task, bug, change, code, test, release, sprint management.

[12] Jira integrates with source control programs such as Clearcase, Concurrent Versions System (CVS), Git, Mercurial, Perforce,[13] Subversion,[14] and Team Foundation Server.

[citation needed] Atlassian provides Jira for free to open source projects meeting certain criteria, and to organizations that are non-academic, non-commercial, non-governmental, non-political, non-profit, and secular.

The process accelerated after the launch of Atlassian Marketplace in 2012, which allowed third-party developers to offer project management plugins for Jira.

[20] BigPicture, Scriptrunner, Advanced Roadmaps (formerly Portfolio), Structure, Tempo Planner, and ActivityTimeline[21][22] are major project management plugins for Jira.
