Verification Engine

We don't list codes. We verify them.

Most coupon sites scrape codes and hope they work. 40–60% of codes on the public web are dead, restricted, or fake. We run a three-layer verification system that tests every code before you see it.

Automated Testing Active
Headless browsers simulate real checkouts across our merchant network every day.
Human Consensus Active
Tens of thousands of trained verifiers with trust scores and screenshot proof.
Fleet Signal Active
Live checkout data from extension users. Ground truth from real transactions.

The Glass Box

Every verdict comes with evidence.

We show the bones. Not just the answer.

Every code carries a Health Score — a freshness-adjusted confidence rating derived from automated tests, human consensus, and real checkout outcomes.

When we say a code works, that's a verdict backed by evidence. A Proof Packet with an evidence chain you can audit.
