Google Open Source

Bringing better technology to the world by promoting open source.

Everyone Benefits

Google believes that open source is good for everyone. By being open and freely available, it enables and encourages collaboration and the development of technology, solving real world problems.

Use

We use thousands of open source projects to build scalable and reliable products.

Release

We have released millions of lines of code under open source licenses for others to use.

Support

We believe that a healthy ecosystem is important for the sustainability of open source for all.

2,000 Projects and Counting

At Google, we’ve always used open source to innovate. We want to give something back; we enjoy being a part of the community. We often release code to push the industry forward or share best practices we developed. But sometimes, it's just fun and interesting code. The list of projects we've released and contribute to is long and continues to grow.

Celebrating young open source contributors

We are pleased to announce the Google Code-in 2018 Grand Prize Winners and Finalists! 3,124 students from 77 countries contributed to 27 open source projects, learning from mentors over the course of 7 weeks. Selected by each of the projects, the Grand Prize Winners are invited on a four day trip to visit Google and San Francisco.

Open sourcing ClusterFuzz

We've open sourced ClusterFuzz, the software behind OSS-Fuzz, a continuous fuzzing service we offer for free to open source projects. OSS-Fuzz has uncovered 11,000+ bugs in over 160 projects in the last two years, and now anyone can integrate fuzzing into their workflow!

A new home for Google Open Source

Free and open source software has been part of Google's technical and organizational foundation since the beginning. We've launched a new website for Google Open Source that ties together all of our initiatives with information on how we use, release, and support open source.
