As this year comes to a close, it is a good time to take a look at the trends of open source license usage in 2020 and compare them to previous years. Our research team has collected information from the WhiteSource database, which includes more than 4 million open source packages and 130 million open source files covering over 200 programming languages, to learn which were the most popular open source licenses in 2020.

One unexpected consequence of the global pandemic is the acceleration of digital transformation across organizations of all sizes.

Open source components have become the basic building blocks of software applications, comprising 60%-80% of the software projects. As open source usage has established itself as an industry standard and the default choice of software production, software development organizations are required to set up an open source strategy.
