Bugzilla

A performant, scalable and secure bugtracker, tried and tested by Mozilla.

About Bugzilla

Bugzilla is a general-purpose bug tracking and testing tool originally developed for the Mozilla project and now maintained independently. It offers advanced search, products and components, milestones, and detailed tracking of defects and enhancement requests, and it is scalable and secure enough for large open-source projects. Released under the MPL, it suits software teams that need a proven, self-hosted defect tracker they fully control.
