Research with a purpose

Better evidence. Better decisions. A healthier open-source ecosystem.

Software is a shared foundation. Understanding who maintains it, where responsibility concentrates, and how security signals change should not be reserved for a few. FOSS Data makes that research easier to explore, question, and put to work.

An initiative from Exodos Labs. Built for maintainers, security teams, researchers, and curious minds.
