7 Best Open Source Project Management Software

By | 9 min read | Published

Project management software helps assign tasks to teams and monitor their progress.

As a project manager, do you ever feel restricted by your current project management software? Are you unable to use the tool to its full potential? Despite paying a subscription fee, do you feel you’re not able to manage your projects and team the way you want?

If such issues seem familiar, maybe it’s time to turn to an open source tool instead. An open source project management solution is fully customizable, as you can tweak the source code to work on unlimited projects per your needs.

Additionally, open source tools have a dedicated community of testers and developers, making bug fixes and troubleshooting more efficient. And when it comes to cost, open source tools are one of the cheapest options for project managers on a budget.

This article highlights the seven best open source project management software (sorted alphabetically) based on user ratings and reviews. (Read the complete methodology here.)

How to choose the right open source project management software for your business

When looking for a fully customizable open source project management system, these are some considerations to keep in mind:

  • Assess the tool’s customizability. The tool you choose should be easy enough to accommodate your project management style. Whether it is Agile, Waterfall, or hybrid, you should be able to change the tool to suit your needs. Also, check if the software is limited to a few project management features and methodologies or if it can accommodate all.
  • Check whether the software offers real-time communication. An open source tool is incomplete if it doesn’t let your team communicate project changes or task updates in real time. Pick a solution that offers built-in chat, call, or video conferencing for seamless communication.
  • Assess how active the software support community is. Many open source software solutions fade out due to the lack of community support and regular updates. When you pick a solution, make sure to assess how active its online community of developers and supporters is.

Common questions to ask while selecting open source project management software

These are some common questions you can ask vendors when purchasing an open source project management tool:

Is your software really open source?

This is an important question to ask because a lot of vendors hand out free software tools without the source code, making it impossible for you to configure and customize the tools without contacting them. When you buy new open source software, make sure to check you’re getting the source code along with it.

How secure is your software?

Being open source can sometimes mean being open to more security threats, as developers might not be actively testing and fixing security issues that arise. When purchasing a solution, ask vendors how robust their security patches are and how often they check for vulnerabilities.

Who else is using this software?

A relatively new open source software can be risky to deploy, especially when you don’t know who else is using it. It’s always a good idea to do your research and find an open source software tool that businesses from your industry are using already.

How did we choose these products? We didn’t—you did

At Capterra, we objectively select and rank products based on a methodology developed by our research team. Some vendors pay us when they receive web traffic, but this has no influence on our methodology.

To find your ideal software match, you need information you can trust—so you can save time, stay on budget, and focus more energy on growing your business. It’s why we vet and verify all our user reviews and recommend only the tools endorsed by people like you.

In other words, our product recommendations are never bought or sold, or based on the opinion of a single individual—they’re chosen by your peers, reflecting the views and experiences of our independent base of software reviewers.


To be considered for this list, products have to:

  1. Have at least 20 unique product reviews published on Capterra within the past two years, with an average rating of 3.0 or higher (as of March 28, 2022). We selected the seven products with the highest ratings to feature in this article.
  2. Offer an open source, stand-alone version of the software with the source code freely available that can be modified and redistributed.
  3. Meet our project management software market definition: “Project management software automates task assignment, resource allocation and milestone tracking for all phases of a project.”

“Best functionality” tool is identified based on the highest user ratings for functionality that a vendor received based on publicly available reviews as of March 28, 2022.

“Most affordable” tool is identified based on the lowest pricing a vendor offered on their website in terms of cost to upgrade as of March 28, 2022.
