Freddy Mallet realizes that code quality management starts to become a critical activity in software development, and that no product on the market provides the ability to perform automated code review in an effective and integrated manner.


Simon Brandhof starts developing the Sonar platform by integrating best-of-breed open source tools for Java.

The two of them are joined in September 2007 by Olivier Gaudin, who was enthused by the Sonar platform’s vision and starts contributing to it.




All three of them decide to combine their expertise and passion to found SonarSource company and take Sonar to the enterprise market.

SonarSource is founded in November 2008 to accelerate development and adoption of the open source Sonar platform. Initial effort is put on making the platform enterprise-ready, adding ground-breaking features such as an API to develop plugin, a built-in access rights mechanism, custom dashboards, hotspots, time machine. . .


SonarSource starts to develop its commercial offering on top of open source Sonar platform.

SonarSource releases its first commercial plugin, Views for projects portfolio management. This will be quickly followed by the release of more commercial plugins such as COBOL, VB6, SQALE… At the same time, the Sonar platform was honored at the Open World Forum 2009 for being one of the most original projects in terms of innovation, quality of execution and potential for value creation.

SonarSource sees both community enterprise acceptance of the Sonar platform, which is now downloaded more than 2,000 times a month.

The company grows in size and, thanks to the success of both the Sonar platform and its commercial offerings, is able to raise the pace of research and development. The results are seen in the release of the C# plugin (June 2011) and the PL/SQL plugin (September 2011).


SonarSource adds commercial editions to its offering, going for enterprise market and the platform is renamed SonarQube.

Based on customer feedback, SonarSource decides to introduce Editions into its commercial offering to respond to the needs of larger companies. At the same time, the platform gets renamed to SonarQube to develop the brand and make sure it can be protected across the world.
