Here's my review of known web-based tracker tools. I'm looking for a generic tool that can be used for anything (i.e. bug tracker, feature request tracker, and tech support/trouble ticket tracker). If you notice any discrepancies, please let me know. Thanks!

I just reworked the way the comparison table is rendered, so updates will be easier to make for me. Another benefit will come with time as I add capabilities to allow users to alert me of changes easier. When updating everything, I added the license column, based on a suggestion from David Besonen. Thanks, David!

I just brought my previous comparison over to my new site. During this migration process, I updated most data, as well. After catching up with the comments/email I've had, I've updated almost everything. I have a handful of new trackers to add, so I'll try to get to those within the next month. Thanks to all who've contributed! I've also created a discussion forum for those who have questions and comments and would like a more interactive way to discuss these things.
