About MantisBT

MantisBT is an open-source bug and issue tracker that balances simplicity with power for software teams. Users can start managing projects within minutes, collaborate with teammates and clients, and stay updated through email notifications on issue changes, resolutions, and comments. Per-project role-based access control, customizable issue fields, notifications, and workflows let it adapt to different teams, and it runs self-hosted on a standard PHP and database stack.
