“The power of Open Source is the power of the people. The people rule.” ~ Philippe Kahn

And, when you combine it with project management, you get an open-source project management solution that offers a flurry of features with customization, full data control, and flexibility.

However, if you’re new, it’s best to go with a more traditional project management solution as they are easy to use and don’t require technical expertise to manage servers. If you’re a newbie, I suggest checking SaaS project management software.

In this article, I’ll go through 9 open-source project management software in detail, with their features and limitations, supported installations, and capabilities to give a clear view of which one suits your needs better.

I have also included 3 additional tools that deserve honorable mentions.

I will now discuss the above open-source project management tools in detail.

1. OpenProject

OpenProject is a top open-source project management software, available under the GNU General Public License v3.

Managers can fully control their project with access to key project management features such as the Gantt chart, Kanban view, team management, work packages, and much more, ensuring complete end-to-end project management.

OpenProject cloud offering comes with a 14-day free trial. 

Once signed up, I found their onboarding useful as they explained every feature to get started. If you feel stuck, you can use OpenProject’s detailed wiki for a smooth setup and operations.

OpenProject supports classic, agile, and hybrid project management. For example, teams can use Kanban and Gantt to visualize and plan their project.

Openproject kanban

OpenProject is fast as it uses Ruby on Rails technology. To handle workload, it uses the workers concept, where each worker handles different tasks, be it HTTP requests or offloading tasks. By default, you get 4 web workers, which can be increased based on project requirements.

As an admin, you can install OpenProject community edition in different ways:

  • Use DEB/RPM packages
  • Install with Kubernetes
  • Use a Docker container for installation
  • Use OpenProject Helm charts

OpenProject limitations:

  • Limited phone support
  • Gantt chart doesn’t support drag and drop
  • Users complain about its lack of flexibility and the hard installation steps

OpenProject Pricing

OpenProject cloud plans pricing starts at $7.25 per user per month. The Basic plan has 25 minimum users and comes with community features and all enterprise add-ons. Additionally, you will get basic email support.

As it is open-source, you also get the community edition for free. However, it is up to you to install and manage, which requires technical expertise.

2. FocalBoard

FocalBoard is a self-hosted project management software and a great alternative to Notion, Asana, and Trello.

Like OpenProject, FocalBoard is a popular project with 23.4K stars on GitHub

I found FocalBoard a great option for project management because it can be used as a personal desktop application (available on macOS, Windows, or Linux), which is great for single users, while the personal server option offers multi-user support.

FocalBoard offers interesting features, including:

  • Plenty of useful templates such as Meeting Agenda, Personal Goals, Competitive Analysis, etc.
  • A user-friendly UI with color-coded elements for easier navigation.
  • Drag-and-drop functionality, like Trello.
  • Support for Kanban, making it ready for agile projects
  • Ability to add filters for easy classification
  • Support for 17 languages including English, Dutch, Portuguese, and others
  • Import from Trello, Asana, Notion, Jira and Todolist
FocalBoard templates

Additionally, Focalboard supports list, calendar, and gallery views as best as possible. Like Trello or Notion, Focalboard supports real-time collaboration and @ tag to catch your teammates’ attention. It also offersh unlimited board creation, customizable templates, and file sharing.

FocalBoard limitations

  • Limited integration options
  • Slow or uncertain development path. For example, currently at the time of writing, FocalBoard doesn’t have any active maintainers. This makes other projects more lucrative, such as Vikunja.
FocalBoard no active maintainer

Focalboard is open-source under the Apache License v2.0. They don’t have any paid plans available, even for their server offering.

3. ERPNext

Under the hood, Redmine uses Ruby on Rails, which provides excellent performance even for complex projects.

As Redmine is free, you can download it and install it on your system. It supports Linux, macOS, Unix, and Windows systems. 

However, you can try it out via its demo site (which is not directly associated with Redmine).

Redmine demo site

When playing with the software, I found the following interesting things about it:

  • It offers project filters to quickly show what you’re looking for
  • Capable of running multiple projects simultaneously
  • Have an activity tab that shows all actions taken by team members
  • Issues are listed in a clean manner, showcasing status, priority, updated, and more.

Redmine limitations:

  • Not user-friendly and requires a lot of patience to use effectively
  • Needs technical expertise to install the backend before you can use Redmine
  • Depends heavily on add-ons and integrations for more features

In short, Redmine excels as a core project management solution and opens the door for customization with its vast library of addons and integrations.

8. Leantime

Leantime is an excellent pick for project management. It offers customizable tools that help you tackle tasks smartly, especially aimed at differently abled professionals such as those with dyslexia, ADHD, and Autism.

Leantime is available under the AGPL-3.0 license (5.4K stars on GitHub). However, not all features are available in the open-source version, such as the AI To Do priority.

As Leantime focuses on usability, it lets you determine a visual experience. Once signed up, you can choose a busier dashboard or a less busy one. It also lets you change readability, select a theme, and set times for proper breaks and work time.

Leantime visual experience choice

So, what else makes Leantime different? It does so by following:

  • Help customize the workflow as per the individual’s needs
  • Comes with Personal Command Center, which helps you stay organized
  • Offers different sections covering different needs, like Data Room to store files, Make to manage goals, and Think to strategize.

Other Open-Source Project Management Software Worth Checking

Apart from the above 9 open-source project management software, I found these 3 to be worth considering:

  1. Wekan: Wekan is a kanban-style open-source project management solution. It is available under the MIT License (MIT). Wekan can be installed on-premise using a Linux bundle, Docker, Kubernetes, or Windows. It also offers JavaScript or desktop solutions.

Key Takeaways
