Achieve project success with versatile open source software for classic, agile, or hybrid management. Features task tracking, Gantt charts, boards, and secure collaboration.
OpenProject is Germany's leading open-source project management platform, supporting classic, agile, and hybrid workflows in a single tool. Gantt charts, Scrum and Kanban boards, time tracking, cost reporting, and built-in wikis cover the full project lifecycle — from initial planning through to billing.
Teams choose between the free Community Edition (self-hosted), Enterprise on-premises, or Enterprise Cloud hosted on EU servers in Germany. A full REST API and webhooks connect to GitHub, GitLab, Jira, Nextcloud, and Slack, while granular role permissions and two-factor authentication keep sensitive projects secure.
Key benefits:
- Gantt charts and work packages with cross-project dependencies and baseline comparisons
- Scrum and Kanban boards with sprint planning, backlogs, and burndown charts
- Time and cost tracking with budgets, hourly rates, and earned value analysis
- Built-in wikis and document management for centralised team knowledge
- Self-hosted or EU cloud — full data sovereignty with no vendor lock-in
- Free Community Edition under GPLv3 for unlimited users and projects
- REST API and integrations with GitHub, GitLab, Jira, Nextcloud, and Slack
All cloud infrastructure is hosted on EU data centres in Germany, with no third-party hyperscalers involved. The platform is fully GDPR-compliant and, as open-source software under GPLv3, every line of code is auditable — self-hosting teams maintain complete control over where their project data lives.
Trusted by Siemens, Deutsche Bahn, Greenpeace, and the Linux Foundation, with 20M+ downloads and 14,800+ GitHub stars.
