Andrew Nesbitt has spent over a decade mapping open source infrastructure. His current project, ecosyste.ms, tracks 12 million packages, 287 million repositories, 24.5 billion dependencies, and 1.9 million maintainers. All of it is open data, built to be used.
This interview covers what Nesbitt actually learned building that dataset, who is consuming it, and what the architecture decisions behind libraries.io taught him before he built ecosyste.ms. The gap between those two projects is where the most useful thinking lives.
If you work in supply chain security, open source sustainability, or dependency analysis, this is primary source material. The dataset exists. The question is what gets built on top of it.
