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]
