Generates realistic fake test data in CSV, JSON or SQL.
Define your columns from a library of hundreds of field types — names, addresses, IBANs, plausible dates, weighted enums — set a row count and download CSV, JSON, SQL inserts or Excel. Realistic data catches formatting and encoding bugs that `test1`, `test2` never will. The free tier gives 1,000 rows per download and 200 API calls a day, so it is for seeding a dev database, not load testing one.
Questions
A genuinely usable free tier with paid plans for volume or team features. Free downloads are capped at 1,000 rows and 200 API requests a day.
Yes. Mockaroo sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
