Wow... lots of great comments here. This is my take (add it to all the other opinions). Some of the pay products are great. Fogbugz, JIRA, etc. But that cost A LOT. Fogbugz is 25 bucks a month per person. We have 100 folks working at my company. There is no way they are going to buy that (I tried). Mantis, Bugzilla, etc are free... but their interfaces are kinda crappy. They are open source projects and were made for programmers by programmers. We tried a few of these and our non-tech staff were confused by them. In the end we created our own simple bug tracker . It doesn't have all the bells and whistles as some of these other systems but it caught on at my company and a few of our clients asked to use it on projects we weren't involved in, so we made a product of it.
