Google Open Source Report Card

 

Open source software enables Google to build things quickly and efficiently without reinventing the wheel, allowing us to focus on solving new problems. We stand on the shoulders of giants and we know it. This is why we support open source and make it easy for Googlers to release the projects they’re working on internally as open source.
