Why we built this
The prices are public. Reading them never was.
Every award and contract action on this site was already published by the U.S. government — scattered across slow systems built for procurement officers, not the public. NSN Explorer renders the same facts clearly: per part, over time, with a link to the source record behind every figure. Transparency, never estimates.
