Mantis is a popular open source web-based bug tracking system. It provides an easy way to create, track and resolve bugs and issues. Mantis also supports release features. However, it is quite limited in its feature scope. Its UI seems to be a little outdated. OpenProject is the best Mantis alternative.

What does OpenProject offer?

OpenProject and Mantis both offer classic issue tracking and release management. OpenProject provides essential project management features that Mantis lacks, including planning and scheduling with Gantt charts, agile project management and cost tracking. You can also organize meetings, have an integrated project wiki and manage forums directly within OpenProject.

No compromises in usability

Software should not only be functional, but also intuitive and visually appealing. In comparison to Mantis, OpenProject invests in a user-friendly interface to make the user experience most enjoyable. The layout is responsive and mobile-friendly.

No compromises in data protection

OpenProject is highly committed to data privacy and information security. Also, if you decide to go with the cloud edition, you can be sure that your data is safe. We do not track our users. OpenProject has its headquarters in the EU, is GDPR compliant by default and stores all of the data in the EU. When using Mantis hosting you have to proactively request using that option.

Everything from a single source

With OpenProject you can not only track and fix bugs, but also plan and execute entire projects. You can visualize timelines, track time and costs, include agile boards, manage documents and meetings or create forums to connect your teams and foster communities.
