Bug Database Comparison
Product	Technicals	SCM	The Good	The Bad
Redmine	Redmine + Mysql, Postgres	cvs, svn, git, more	Very clean UI, completely customizable priorities and statuses, lots of plugins	Setting up roles and workflows can be cumbersome, Ruby
Mantis	PHP + Mysql (postgres and other db's are 'experimental')	NONE	Simple straightforward bugtracking, has been around for nearly 10 years, IN YOUR FACE list of issues - no digging around for things	Ugly, sub-optimal UI, cannot modify Resolution, Priority, and other attribute values
Jira	Java 1.5 SDK+	Fisheye cvs, svn, perforce, git	Very feature complete, "Agile" stuff if you are into deadlines	EXPENSIVE for > 10 people. A monster black hole. Agile cards are weird, and don't go away. Issue listing is always a search. Many clicks to see issues
Trac	Python + SQLite or Postgres (mysql experimental)	svn	All the cool kids use it,	Filtered search for listing,wiki is not terribly useful, and can't be disabled. No defaults, milestone oriented. Many clicks to see issues, command line interface for basic tasks like renaming milestones, etc.
ActiveCollab	PHP + MySQL	svn (in Corporate version)	Very feature rich - complete project management package, pretty, Ajaxified, nice GUI editor when editing tasks	Overbearying organization - Project -> Milestone -> Ticket. Drill Baby, Drill. Many clicks to see issues.
FlySpray	PHP + MySQL, Postgres	NONE	Jabber Integration, flexible & easy configuration of types of reports, resolutions, configuration, more	Not templated, poor code. Low activity project.
