The State of Public Code: How Governments Worldwide Contribute to Open Source
Bastien Guerry

How much do governments actually contribute to open source? The State of Public Code, a Software Heritage initiative, provides the first large-scale, data-driven answer: an analysis of the world’s public sector open source activity, built on the Software Heritage archive (March 2026 snapshot) and published as open data under CC BY 4.0, with a documented and reproducible methodology.

Measuring What Matters: Closing the Gap Between Open Source Policy and Implementation
Omar Mohsine, Sachiko Muto, Bastien Guerry, Lea Beiermann

Interest in open source at the policy level has grown considerably in recent years. What's still missing is a shared understanding of what it takes to make that endorsement operational. This panel brings together three evidence bases for closing that gap: new research identifying 13 concrete capacity indicators that separate policy intent from practice; the UN's Open Source Enablement Compass, which is turning that kind of research into a yearly benchmarking tool for governments worldwide; and Software Heritage's State of Public Code, which tracks what governments actually contribute, not just what they claim. Together, they ask: what would it take to move open source in government from policy to evidence-based action?
