Redmine is a free and open source, web-based project management and issue tracking tool. It allows users to manage multiple projects and associated 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.[2]

Following concerns with the way the feedback and patches from the Redmine community were being handled[8] a group of Redmine developers created a fork of the project in February 2011.[9] The fork was initially named Bluemine, but changed to ChiliProject.[10] After the leader of the fork moved on from ChiliProject in 2012[11] and development got stuck,[12] the project was officially discontinued in February 2015.[13]

Another fork of ChiliProject called OpenProject is being actively worked on.[14]
