What SimplyLabs is

The directory exists because listings in this market change faster than the documentation behind them. A source can publish a certificate for one batch and nothing for the next twenty. Our job is to keep an auditable trail: what was published, when, by which laboratory, and against which batch.

Records are compiled from public sources: storefront listings, published certificates, laboratory identifiers and corrections submitted by researchers. Anything unverified is labelled unverified. Where a source publishes its own in-house test, it is recorded as an in-house test — not as independent testing.

We take no placement fees, run no affiliate links and accept no sponsored status. The index does not sell anything and does not advise on use. It is a documentation registry for people who read paperwork before they read marketing.
