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.[3]

Redmine is written using the Ruby on Rails framework.[4] It is cross-platform and cross-database and supports 49 languages.[2]

Redmine's features include the following:[5]


As of 2008, there were more than 80 major Redmine installations worldwide.[6] Among the users of Redmine is Ruby.[7] In 2015, Redmine was the most popular open source project planning tool.[8]


Following concerns with the way the feedback and patches from the Redmine community were being handled[9] a group of Redmine developers created a fork of the project in February 2011.[10] The fork was initially named Bluemine, but changed to ChiliProject.[11] After the leader of the fork moved on from ChiliProject in 2012[12] and development and maintenance had been announced to shut down,[13] the project was officially discontinued in February 2015.[14]

Another fork of ChiliProject called OpenProject is active since 2015.[15]
