Redmine
Flexible open-source project management and issue tracking web application
About Redmine
Redmine is a free, open-source project management and issue tracking web application built on Ruby on Rails and released under the GNU GPL v2. It supports multiple projects, role-based access control, Gantt charts, per-project wikis and forums, time tracking, and integration with Git, Subversion, and other version control systems. Teams self-host it on their own servers, and the project has shipped regular releases since 2006, most recently the 7.0 line with native webhooks.
