Mockaroo
Design a realistic dataset in the browser and export it as CSV, JSON or SQL.
What it is
Mockaroo lets you define a schema field by field from a large library of realistic data types, then generate and download up to millions of rows as CSV, JSON, SQL insert statements or Excel. It also hosts mock APIs backed by the same generated data.
Best for
Where it is strong
- No code required — an analyst or tester can design a dataset themselves.
- Very large library of realistic field types including regional formats.
- Formula fields allow simple business rules between columns.
Where it falls short
- Referential integrity across related tables is limited.
- Free-tier row limits are low for realistic volume testing.
- Data is generated on a third-party service, which needs a privacy check for schema sensitivity.
Pricing
From $60 per year (indicative, Silver)
Free tierFree tier: Free for up to 1,000 rows per download and a limited number of saved schemas.
What drives the bill: Cheap for what it does; higher tiers raise row limits and add API quota.
