OpenProject - Open Source Project Management Software | WarmIndex

OpenProject is the leading open source project management software for classic, agile, or hybrid project management in secure environments.

🚀 Overview

OpenProject is a powerful web-based platform that enables teams to plan, track, and collaborate on projects using Gantt charts, agile boards, and more. It addresses the challenges of project coordination by providing tools for task management, time tracking, budgeting, and team collaboration, all while ensuring data sovereignty and security.

This project is built for project managers, development teams, businesses, universities, public sector organizations, and NGOs who need a flexible, transparent alternative to proprietary tools. It's particularly suited for those prioritizing self-hosting, open source principles, and compliance with data protection standards.
