Overview

Mockaroo lets you generate realistic fake datasets in JSON, CSV, SQL, or XML with fully customizable schemas. You define field names and types (name, email, phone, etc.) and the API returns rows of structured mock data. An API key is required and the free tier allows up to 1,000 rows per request.

💡

Beginner Tip

Design your schema visually on the Mockaroo website first, then copy the generated API URL to use in your code — this is much easier than constructing the schema payload by hand.
