The OpenChain Project maintains the industry-standard for the key requirements of a quality open source compliance program. Companies, governments and non-profit organizations use our standard for open source compliance every day to build trust in the supply chain.

We support our community with extensive reference material, a simple online questionnaire for conformance, and a vibrant international community. You can learn more about the details of the project and how it is organized in our FAQ. You can go straight into the free conformance process on our Get Started page. Meanwhile, you will find some of our key reference resources on this page.
