Self-hosted project management covering classic, agile and hybrid work, for organizations that need transparency and full control of their data.

Classic, agile and hybrid work all fit inside OpenProject, web-based project management for teams and organizations that require transparency, flexibility and data sovereignty. Projects, portfolios, products, tasks, bugs, roadmaps and team collaboration live in one platform rather than in a separate subscription for each of them.
It is aimed at organizations wanting an open source, enterprise-ready alternative to Jira, MS Project, Monday, Asana and YouTrack while keeping full control of their data and infrastructure. The project reports use by enterprises, public institutions and highly regulated industries.
The platform stretches across several ways of running work.
- Agile and classic planning: boards for Kanban, Scrum and SAFe alongside Gantt charts for scheduling.
- Portfolio management: project and portfolio views, extended to product and release planning.
- Time and cost: time tracking, cost reporting and budgeting attached to the work itself.
- Collaboration: wikis, forums, news, and meeting agendas with their minutes.
- Integrations: Nextcloud, XWiki, GitHub and GitLab among others.
