Key features of open-source project management software

Look out for the following key capabilities when shopping for an open-source project management tool.

Source code availability and community support

Open-source tools are community-backed. Their source code is usually available on GitHub, allowing users to contribute to the project. Source code enables users to use, modify and customize the software to meet their specific needs. They can also submit bug fixes and request features. Before selecting a tool, check the project’s community:

  • Is the community active?
  • How often do they roll out an update?
  • What are the project track records?
  • How easily modifiable is the source code?

Answering these questions will get you started.

Project planning and task management

Project planning is necessary to define project goals, objectives and milestones. The software should provide tools to create project plans, Gantt charts and other planning tools. With task management capability, managers can break a project into smaller tasks and assign them to team members. The software should provide an easy-to-use interface for creating, assigning and tracking tasks. It should also allow users to prioritize tasks, set deadlines and track progress.

Cost savings

Open source project management software is often free or very low cost. This makes it an attractive option for businesses looking for a cost-effective solution for their project management needs.


Collaboration is essential for effective project management. Open-source project management software often includes collaboration features such as team messaging, file sharing and real-time updates. The software should provide a platform for team members to communicate, share files and work together. It should also allow for easy feedback and approval processes.

Resource management and time tracking

The software should allow you to manage resources such as people, equipment and materials. It should also provide reports on resource usage. Time tracking is also necessary to ensure projects are completed on time and within budget. The software should allow team members to track their time spent on tasks and provide usage reports.

How do I choose the best open-source project management software for my business?

The best open-source project management software depends on your needs and preferences. To determine the best solution for your company use case:

  • Identify your goals and project management needs.
