How do I mock the Amazon DynamoDB API locally?

Install stunt, add a one-service block to stunt.yaml (adapter: embedded:dynamodb-style), and run stunt up. You get a local, stateful stand-in for Amazon DynamoDB API 2012-08-10 — 1 routes over rest — with no remote account, no network, and no bills.

Is the Amazon DynamoDB API mock data synthetic?

Yes — entirely. The adapter returns generated data only; stunt's adapter lint rejects real-looking secrets and PII at build time. It simulates the shape and behavior of Amazon DynamoDB API (routes, status codes, pagination, webhooks), never real records.

The embedded: source extracts this adapter from the binary — no git clone, fully offline.

how to mock the Amazon DynamoDB API locally

Install stunt, paste the service block above into stunt.yaml, run stunt up — then point your client at localhost instead of Amazon DynamoDB API. It works offline, keeps state across requests and restarts, and every response is synthetic: the route shapes, status codes, pagination, and webhook delivery follow the real Amazon DynamoDB API 2012-08-10 surface — the data is fake, the behavior is real.
