Guardian Digital's Open Source Commitment

Our Unwavering Commitment to Open Source

Governments and corporations are realizing that open source is often the best way to develop software. Some of the biggest companies in the world are not only using open source software, but open sourcing their own code as well. In short, open source is now a core part of how software is created not just by software companies, but by every kind of company.
