OpenProject

OpenProject is the leading open-source project management software, empowering teams to achieve great things together. With over a decade of development, it provides a comprehensive suite of tools for planning, scheduling, and tracking projects from start to finish.

OpenProject supports both classic and agile project management, featuring Gantt charts, work packages, sprints, kanban boards, and a built-in wiki. Its time tracking, cost reporting, and budgeting capabilities set it apart from lighter alternatives — making it suitable for enterprises and NGOs managing complex, multi-team projects. The GitHub integration links work packages directly to pull requests for seamless developer workflows.

Available as a self-hosted Community edition (free) or Enterprise cloud/on-premises edition with premium support and add-ons, OpenProject is trusted by organizations worldwide. With features including forums, meeting agendas, bug tracking, and roadmaps, it is one of the most feature-complete open-source alternatives to Jira, Asana, Trello, and Monday.com.
