OpenProject

OpenProject is an open-source project management web application. It provides work package tracking, Gantt chart scheduling, Scrum and Kanban boards, time tracking, cost reporting, wiki pages, and document management. The software is written in Ruby on Rails (backend) and Angular (frontend), and is released under the GPLv3.

OpenProject is available as a free community edition and as a commercial enterprise edition with additional features including LDAP group synchronization, two-factor authentication, and custom actions. Both self-hosted and cloud-hosted deployments are supported.

OpenProject is a component of the German government's OpenDesk productivity suite, developed by the Center for Digital Sovereignty in Public Administration (ZenDiS) as a Microsoft 365 alternative for the public sector.
