OpenProject

OpenProject is a fully open-source project management platform that gives you control over your data and infrastructure. You can run it on your own servers or use their cloud hosting, with Gantt charts for timeline planning, Kanban and Scrum boards for Agile workflows, time tracking, and budget tracking all built in. Because it's open-source, you can modify the code, extend it with custom features, or integrate it deeply into your existing systems without vendor lock-in.

OpenProject appeals to organizations that prioritize data sovereignty, technical teams that want to self-host, and companies that need customization but can't afford the expensive consulting hours of enterprise tools. The open-source community is active, and paid support is available if you need it. The trade-off is that you're responsible for hosting, backups, and updates if you self-host. If your team has infrastructure expertise and values control, OpenProject gives you the flexibility that SaaS tools can't match.
