Redmine is a free and open source, web-based project management and issue tracking tool. It handles multiple projects and subprojects. It features per project wikis and forums, time tracking, and flexible role based access control. It includes a calendar and Gantt charts to aid visual representation of projects and their deadlines. Redmine integrates with various version control systems and includes a repository browser and diff viewer.

The design of Redmine is significantly influenced by Trac, a software package with some similar features.

Redmine is written using the Ruby on Rails framework. It is cross-platform and cross-database and supports 34 languages.



Redmine is reported to have more than 80 major installations worldwide.[2] Among the users of Redmine are Ruby.


Following concerns with the way the feedback and patches from the Redmine community were being handled[3] a group of Redmine developers created a fork of the project in February 2011.[4] The fork was initially named Bluemine, but changed to ChiliProject. After the leader of the fork moved on from ChiliProject in 2012[5] and development got stuck[6] since then, the project was officially discontinued in February 2015.[7] However, there is a fork of ChiliProject called OpenProject, which is being actively worked on.
