Open Source at AWS

Amazon is part of the open source community: We've been contributing to hundreds of projects for over a decade. We continue to widen our open source collaboration, increasing code contributions and helping to sustain the overall health of open source. We are committed to working with, supporting, and contributing to new and existing open source projects that provide value to our customers and partners. AWS has always aimed to take technology that was traditionally cost-prohibitive and difficult for many organizations to adopt, and make it accessible to a much broader audience. Open source is just one more way that we seek to make technology more accessible to everyone.
