What Redmine is
Redmine is a free, open-source web application for project management that can be self-hosted. One instance can manage multiple projects, with separate roles, visibility settings, and enabled modules for each. Teams can define issue types and statuses, then configure workflow transitions by issue type and role. Gantt charts and calendars use issue dates, while time entries can be reported by user, issue type, category, or activity. Redmine also includes project wikis and forums, news, document and file management, feeds, and email notifications. Its repository browser supports Subversion, CVS, Mercurial, Bazaar, and Git. The REST API offers basic create, update, and delete operations for documented resources in XML and JSON. Redmine runs on many Unix, Linux, macOS, and Windows systems where Ruby is available, but it does not support JRuby. It is released under GNU GPL v2. The project points users to forums and IRC for support, and lists the 7.0.x branch as its latest stable release.
