"MantisBT - Open-Source Tracking Software Ideal for Small Teams"
4/5
What do you like best about MantisBT?

MantisBT is very intuitive and straightforward if your team does not have much need for customization or integrations with other software. MantisBT is a solid, reliable database for tracking bugs and issues. Review collected by and hosted on G2.com.

What do you dislike about MantisBT?

Let's get the obvious out of the way - the interface is dated. Usually this isn't an issue, but when you're working intensively with a specific software, aesthetics are an unexpected yet appreciated aspect. Additionally, my team has found that when needing more flexibility (integrations, workflows, etc) MantisBT requires much more technical acumen to implement the desired changes.

It is very versatile and configurable, useful for traditional methodologies, easy to share with end users, giving them different permissions and the ability to hide comments. Review collected by and hosted on G2.com.

It does NOT work well for Agile methodologies, this should be reviewed. Since it is not possible to have easier and more agile searches, and there are no ways for card processes or sprint planning. Review collected by and hosted on G2.com.

1. Easy to find issues by the search and sorting.

2. Easy to manage.

3. Email notification. Review collected by and hosted on G2.com.

What do you dislike about MantisBT?

1. No fancy statistic diagram on dashboard, only table with figures. (The boss loves diagrams)

4. No auto-reply robot and online chat messenger to deal with critical issues for my client. Review collected by and hosted on G2.com.
