Jira is a proprietary issue tracking product developed by Atlassian. It provides features for bug tracking, issue trackening and agile project management.

The Product

Jira is part of a family of project management and collaboration software developed by Atlassian. It is one of the most popular project management tools, but is also often criticised for being slow and bloated. The tool was originally open sourced but Atlassian decided to move to a proprietary model and build a business around it.
