GitHub Issues vs Redmine

GitHub Issues has no write-up on Specifiction yet; its figures are above.

Redmine is an open-source web application for managing projects, available for self-hosting. A single instance can manage multiple projects, each with its own roles, visibility settings, and enabled modules. Teams can define issue statuses and types, then set workflow transitions by issue type and role. Gantt charts and calendars use issue dates for planning, and time entries can be reported by user, issue type, category, or activity. Collaboration tools include project wikis and forums, news, document and file management, feeds, and email notifications. The repository browser supports Subversion, CVS, Mercurial, Bazaar, and Git. Its REST API provides basic create, update, and delete operations for documented resources in XML and JSON. Redmine is released under GNU GPL v2 and costs nothing for self-hosting. It should run on most Unix, Linux, macOS, and Windows systems where Ruby is available, but it does not support JRuby. The project directs users to forums and IRC for help and discussion. The download page identifies the 7.0.x branch as the latest stable version, with new features, bug fixes, and security updates.
