RateShip

Every shipping provider models the same three things differently: what a rate is, what a label is, and how they tell you something changed.

Swapping providers, or running two at once for redundancy, usually means rewriting the integration and re-verifying every webhook signature by hand.

RateShip normalizes rates, labels and webhook verification into one typed API. Providers are adapters, so adding or replacing one is a config change.

It ships with no runtime dependencies, so it runs in a serverless function without pulling in a large dependency tree of its own.

Teams price against three carriers at checkout and switch defaults without touching product code. A bad field is a compile error, not a support ticket.
