Tuleap

Tuleap is an open-source platform built for organizations running scaled agile practices like SAFe, along with traditional Scrum and Kanban. It includes planning and tracking across multiple team levels, portfolio management, artifact linking across sprints and releases, and integration with DevOps tools. The breadth means it can handle complex organizational hierarchies and large-scale program coordination.

This is best for enterprise and mid-market teams practicing agile at scale across multiple teams or programs. If you're coordinating dozens of developers across multiple squads or running a product portfolio, Tuleap's planning, tracking, and cross-team visibility justify the complexity more than simpler agile tools.
