Choosing a shipping rules app: the checklist that matters
Every app in this category can hide and show rates. The questions that separate them: What happens when a rule is wrong? Can you test before publishing? Can you undo? Can you prove what changed and when?
To be fair to the incumbents: ShipperHQ's carrier-rate breadth is real, and the cheap apps are genuinely cheap. The safety column is where Drydock stands alone.

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.
Build this rule and test it in five minutes
Free plan includes the full simulator with traces. No card, nothing touches your live checkout until you publish.
