About & credits
SpecCheck audits a website URL against The Website Specification, a platform-agnostic checklist of the technical features a good website should have, and grades each item pass / partial / fail / N·A with the evidence behind every result. Its differentiator is the Agent Readiness category that existing auditors don't cover.

What we changed
CC BY 4.0 requires us to indicate changes. We have adapted the checklist into automated probes: each spec item is mapped to an HTTP / FILE / DNS / TLS check (and, where applicable, a rendered or API-based one) that produces a concrete result with evidence. The wording, thresholds, and pass / partial / fail logic are our interpretation of the spec; every result links back to its source spec page so you can read the full requirement.
Accuracy & reporting a wrong result
Many checks are deterministic, but some are heuristic and read a signal from outside the site, so they can miss context a human would catch. Where a check is less certain, the result is flagged auto-checked, verify manually, and the evidence behind every verdict is shown so you can judge it yourself. If a result still looks wrong, tell us: fail and partial rows carry a “Think this is wrong? Report it” link that opens a prefilled email with the check, the scanned URL, and the verdict, or write to [email protected]. Every report is a chance to fix the check, so the next scan is more accurate.
