The Bug Genie is a user-friendly and powerful PHP5.3-based bug tracker/bug tracking tool with features such as project management, VCS integration (git, svn, hig), wiki and more. Ready to use out-of-the-box, and easy to install.
Patchy extends the Mantis bug tracking system to allow users to submit patches which are then autotested before being queued for approval. Please download, try the live demo (Home Page link above), join the announce mailing list for updates or help code!
