FAQ : Let's go back to the basics of open source

What is open source?

Open source refers to software whose source code is made available to the public, allowing anyone to consult, modify, improve and redistribute it.

This development model is based on open collaboration between developers and users, and is founded on the principles of transparency, collaboration and community.

Is open source free?

Open source is often associated with free software, but this is not always the case.

The term "open source" refers to the availability of source code and the freedom to modify and redistribute software, but not necessarily to its cost.

Are there any advantages to open source?

The main advantage of open source software is that it is highly configurable and scalable, to suit your needs as closely as possible.

But under the guise of being free or low-cost, it can involve high hidden costs, particularly in terms of hosting and maintenance work.

What's the best open source software?

The best software is the one best suited to your business and your needs!

If the tool you select matches the complexity of your projects and your in-house IT skills, then you've found the best software! 👏

Our selection criteria

To prepare this comparison of open source project management software, we took into account :

  • open source character, of course,
  • the software's reputation,
  • functional richness, in particular :
    • task allocation,
    • task filtering,
    • definition of deadlines,
    • document sharing,
    • integrated communication tools (chat, comments, etc.),
    • access control,
    • multiple methods and views, such as Kanban, Gantt, etc,
  • added value proposition, whether in terms of interoperability with other software or complementary functionalities,
  • interface ergonomics, which is not often the strong point of open-source software, due to the contribution of multiple developers, some of them volunteers,
  • the presence of an active community, providing potential support, but above all helping the tool to evolve with new technologies,
  • the price: free, paid, answer D?

Our latest tips for choosing your software

Project management concerns companies of all sizes, from the moment they have teams with mission assignments, a budget and deadlines to meet. Increasingly agile and collaborative, project management requires the right tools and the right expertise.

If you're looking for an open source solution for :

  • its open code, which makes it a flexible tool that can be adapted to your business needs and changes in your company ;
  • the fact that you don't have to buy a license, and its community nature, particularly for sharing knowledge around its development;

and if you have the skilled resources in-house (an IT department) to modify and adapt the code and carry out the necessary updates, open source project management software may be the solution of choice.

But if you're looking for a free project management tool, if that's why you're turning (like others) to open source, you should know that free software isn't really free, since you have to :

  • sometimes host it on your own servers ;
  • often pay for access to the full version and all its features;
  • always spend time on updating, maintenance and technical support.

Should you take the plunge into open source project management?

Choosing the right project management software is essential for optimizing the coordination and monitoring of activities within your company.

Whether you opt for an open source solution or recognized alternatives, the important thing is to select a tool that not only meets the specific requirements of your projects, but also the culture and capabilities of your team.

Take the time to test these tools, assess their impact on your day-to-day operations, and consult your team for an informed choice tailored to your needs. 💪
