OpenSourceCheck

A public registry of AI security audits for open source

After the July 2026 Coldcard hack — ~$89M drained through a five-year-old software-PRNG seed bug in open-source firmware — one fact is inescapable: attackers already run frontier models against public code. OpenSourceCheck is where defenders publish their audit runs in the open: signed, human-validated, and reproducible.

Read this first

An entry means a model was run over a stated scope and a human triaged what it reported. It is not a safety certificate. A clean run can miss real bugs — Coldcard proved exactly that.
