Test Data — entry 011 of 19
Mockaroo
Mockaroo lets you design a custom data schema from 200+ field types (names, addresses, dates, custom regexes, and more) in a web UI, then generate up to 10 million rows of realistic-looking test data as CSV, JSON, SQL, or Excel. Downloads from the browser are unrestricted on every plan, but the companion REST API (my.api.mockaroo.com) requires an X-API-Key header or key query param, and the free tier caps API usage at 200 requests/day with a 5,000-record ceiling per call on every plan. It's a common fixture-generation tool for QA and load-testing pipelines that need bulk, schema-shaped fake data rather than a handful of ad-hoc records.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
