Mantis BT popular open source bug tracking application. It has a broad range of features, such as issue tracking, project wikis and more.

So why look for an alternative?

First, Mantis BT's user interface is not very user-friendly. It requires some comprehensive skill set to optimize and modify the interface for your needs. As a small to mid-sized business, using Mantis BT might just be an overhead. Especially if you just look for an easy-to-use bug tracking system.

Second, if you want to customize Mantis BT, even when it's a minor modification, get ready to spend a few hours inside Mantis BT adjusting various settings.

If you are looking for a Mantis BT alternative, Usersnap Classic is an ideal replacement.
