With an estimated market value of €25 to €30 billion within the European Union in 2022 (1), open-source is experiencing increasing popularity. Discover how these collaborative software solutions are transforming the technological landscape and offering numerous opportunities.
What is open-source software?
Open-source software is a type of software whose source code is made available to the public, allowing anyone to view, study, modify, and distribute it freely. The central aspect of open-source lies in transparency and collaboration.
The term "open-source" was first introduced in 1998 with the release of the source code for the Netscape Navigator web browser. This initiative, known as the Open Source Initiative (OSI), gave birth to a movement that revolutionized the software industry.
Open-source software is generally distributed under specific licenses such as the GNU General Public License (GPL) or the MIT License, which ensure user rights and promote continuity of openness and freedom.
The growing adoption of open-source software is largely due to its ability to stimulate innovation, offer flexible and customizable solutions, and the power of the developer community that supports it.
Open-source in numbers: a booming market
According to a study conducted by Markess, the open-source market in France is experiencing significant growth, representing nearly €5.9 billion and over 60,000 direct jobs in 2022. This constantly evolving sector is expected to continue expanding, with an average annual growth forecast of 7.8% by 2027. Open-source accounts for approximately 11% of the digital market in France for the year 2022. This highlights the increasing importance of open-source software in the country's digital economy.
What about contributors? According to Github (a web solution that facilitates storage, management, and tracking of source code changes for developers), the European market has over 3 million open-source developer contributors. This strong presence of open-source developers in Europe reflects the commitment and involvement of the European community in promoting and developing open-source software.
Focus on well-known open-source software
This open-source development model has generated some of the most widely used applications and cloud platforms today. Examples include:
Linux (operating system)
LibreOffice (office suite)
Mozilla Firefox (web browser)
MySQL (database management system)
Git (version control system)
Wordpress (content management platform)
Android (mobile operating system developed by Google)
Open-source software vs. proprietary software
In the realm of software, choosing between open-source and proprietary software can have a significant impact on how businesses operate and innovate. The table below compares these two types of software:
Critères | Logiciel open-source | Logiciel propriétaire |
Licences | Open and flexible licences | Proprietary licences |
Cost | Often free or reduced cost | Variable costs, sometimes high |
Integration | Ability to integrate with other systems | Often specific integration |
Security | Open audits and source code transparency | Dependency on the vendor for security updates |
Maintenance and support | Community support and discussion forums | Support provided by the vendor, often with maintenance contracts |
Features | Wide range of features due to community contribution | Features often determined by the vendor |
Customization | Open-source code allows for customization | Limited by the customization options provided by the vendor |
The choice between open-source software and proprietary software depends on the specific needs of users and businesses. They may opt for proprietary software to benefit from solid technical support and seamless integration, while developers or more technically inclined users may prefer open-source software for its flexibility and transparency. There are also cases where both types of software can be used together.
Advantages of open -source software for businesses
Open-source offers numerous advantages to businesses, enabling them to thrive in a constantly evolving software environment.
