Here are some good web applications and desktop software for “software defect management”, otherwise know as bug tracking.
- Mantis – looks good and open-source, but somewhat difficult to install.
- Bugzilla – from Mozilla. Pretty great, but more than what I need. Also difficult to install. I was able to easily install Free Virtual Bugzilla Server, but it’s just local.
- Sifter – not open-source; costs money.
- Lighthouse – not open-source; costs money.
- BugNET – built using the ASP.NET, boo!
- eTraxis – PHP-based; looks promising.
What’s your feedback on these, have you used any? Know any other good ones?

Chip suggested JIRA, which looks good, but is more of an enterprise solution. Costs lots of money, is complex to setup, and it’s Java (yuck). http://www.atlassian.com/software/jira/
