If you’ve never heard of bugzilla you’ve probably been under a rock for a very long time. It is one of the best bug tracking systems out there but it does run off the web which can be impractical at times. Enter Deskzilla, the dekstop version of bugzilla.
We use bugzilla not just for bug tracking but also for case work and rule evaluations at ExchangeDefender so its more than just a bug tracking system. Download it and check it out.
Update: Just had a chance to deploy it. Wow. $100 for a Java-based interface to Bugzilla? No thanks, skip this one and stick with the web.
