Andrew Nesbitt has spent over a decade mapping open source infrastructure. His current project, ecosyste.ms, indexes 12 million packages, 287 million repositories, 24.5 billion dependencies, and 1.9 million maintainers. That is not a dashboard. That is a census of the software supply chain.
The interview covers what Nesbitt actually learned building this, who is consuming the dataset today, and how the data is structured for others to build on. The dependency graph alone at 24.5 billion edges raises hard questions about which maintainers are load-bearing for global infrastructure and whether anyone is watching them.
Read the full transcript or listen to find out how ecosyste.ms evolved from libraries.io, what the oss-taxonomy project is trying to solve, and what Nesbitt thinks is still missing from the open source metadata picture.
