Block the checkouts that should never happen

Chargebacks, legal exposure, undeliverable orders — some checkouts cost more completed than abandoned. Drydock validation rules block checkout with your message when conditions match.

They fail open by design — an engine problem can never lock your store — and uniquely, they can be simulated: type the address, see the block and the exact conditions that fired, before a customer ever does.

Test first. Undo after. Always.

Drydock runs every draft rule against a synthetic checkout — real products, any address, any customer — and shows a trace of every condition with the actual values compared. Save good scenarios as test cases and they re-run on every publish, so a rule that changes an outcome gets flagged on the publish screen instead of at your checkout. Every publish is an immutable version with a diff, and restoring a previous version is one click.
