Google Open Source
Bringing better technology to the world by promoting open source.
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.
We use thousands of open source projects to build scalable and reliable products.
We have released millions of lines of code under open source licenses for others to use.
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.Explore projects
