Ecosyste.ms provides a set of free, open resources for those working to sustain and secure open-source software. We publish open data and APIs that map software interdependencies, offering insights into usage, creation, and impact. Ecosyste.ms serves as infrastructure for researchers, policymakers, developers, and funders, helping them better understand the open-source ecosystem.

Ecosyste.ms combines data from package registries, software repositories, vulnerability databases, containers, and operating systems. By integrating this information, we create a comprehensive view of open-source software, identifying critical software ecosystems that form the backbone of our digital infrastructure.
