Redmine
Redmine is a long-running, free and open-source web-based project management and issue-tracking tool written in Ruby on Rails. Released in 2006 by Jean-Philippe Lang, it offers flexible issue tracking with custom workflows, Gantt charts, a calendar, time tracking, per-project wikis and forums, document management, and multi-project support, all extensible through a large plugin ecosystem (including agile boards). It is GPL-2.0 licensed and self-hosted on your own server.
Our verdict
A battle-tested, endlessly extensible open-source issue tracker (since 2006) that remains actively maintained (5.1.x/6.0.x/6.1.x releases in 2026) and is a default choice for self-hosted technical teams. Held back by a dated default UI and reliance on plugins for agile/modern features.
