UCP Conformance Check (unofficial)

Independent tool. Not affiliated with, endorsed by, or a substitute for the official UCP conformance suite.

Fetches /.well-known/ucp server-side and runs the discovery + profile-structure checks. This is a preview — the full 37 kill-rate-validated checks run in the CLI.

Run the full suite

37 checks across checkout, order, discount, catalog, cart, totals — each proven to catch its own defects, each citing a spec clause.
