Why is OpenProject better than Mantis for project management

If you are looking for a more modern open source alternative to Mantis, take a look at the following advantages and learn why OpenProject is the best Mantis alternative.

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
