Jira
JIRA Software is a proprietary issue tracking product, developed by Atlassian. It provides bug tracking, issue tracking, and project management functions. Although normally styled JIRA, the product name is not an acronym, but a truncation of Gojira, the Japanese name for Godzilla, itself a reference to JIRA's main competitor, Bugzilla. It has been developed since 2002.
The JIRA Action Pack allows you to build visual workflows to fully automate common JIRA related activities.
