Redmine

Redmine is a flexible project management web application focused on issue tracking and team collaboration. Built with Ruby on Rails, it supports multiple projects and works with several database backends.

Key Features

• Multiple projects with per-project configuration
• Flexible issue tracking with custom fields and workflows
• Role-based access control (RBAC)
• Gantt chart and calendar views
• Time tracking and reporting
• Wiki and forums per project
• Documents and file management
• Email notifications, feeds, and issue creation via email
• Source control integration (including Git and Subversion)
• Authentication options including LDAP and self-registration

Use Cases

• Managing software development projects with issues, milestones, and timelines
• Running internal IT/helpdesk-style ticketing with roles and custom workflows
• Coordinating documentation and discussions using per-project wiki and forums

Limitations and Considerations

• Plugin and theme compatibility can depend on the specific Redmine version
• The official shared demo referenced by the community is operated by a third party

Redmine is well-suited to teams that need a proven, extensible tracker with strong project structure and permissions. Its cross-database support and mature ecosystem make it a common choice for long-running, process-oriented projects.
