How it works

We collect research data

Pulling in millions of papers and metadata from sources like Crossref and OpenAlex, so we can see how research is built

We link software and science

We match mentions of open-source projects in publications to the code and people behind them, uncovering the invisible infrastructure of modern research

We reveal the bigger picture

Showing where science depends on fragile or under-maintained software, helping funders, institutions, and communities invest where it matters most.

Part of the Ecosyste.ms Platform

We provide this essential service at no cost as part of the broader ecosyste.ms initiative to support and secure critical digital infrastructure
