Mockaroo

Overview Mockaroo is a test data generator and API mocking tool that creates realistic datasets in CSV, JSON, SQL, Excel, and XML formats. It helps developers and testers simulate production-like data without writing any code. Unlike data mocking libraries that require programming knowledge, Mockaroo works through a web interface where users define field types and download ready-to-use data. It is available as a hosted service or as a Docker image for private cloud deployment. Key Benefits Generate up to 1,000 rows of test data per file on the free plan with no daily download limit from the browser. Create mock APIs with full control over URLs, responses, and error conditions to parallelize front-end and back-end development. Download data in SQL and CSV formats that load directly into test databases without transformation. Access all features on every plan, including AI-powered field generation and custom data types. Automate data generation via a RESTful API using saved schemas and curl scripts after signing in with Google. How It Works You open the schema builder on the web interface, add fields by choosing names and data types like First Name, Email, or IP Address, and set options such as blank percentage. You select the output format (CSV, JSON, SQL, Excel, or XML), choose the number of rows, and click Generate Data to download the file. For mock APIs, you design endpoints with custom responses and error conditions, then point your UI code at the provided mock URLs. Use Cases Front-end developers building UI prototypes that need realistic API responses to uncover flow and timing issues early. QA engineers filling test databases with high-volume, varied data to simulate production conditions and catch edge-case bugs. Data engineers generating sample datasets in SQL or CSV format for pipeline testing and schema validation. Back-end developers testing API endpoints with controlled error conditions and varied payloads before release. Product demo teams preparing realistic-looking data to showcase new features to stakeholders more effectively. Why Choose This Product Mockaroo best suits developers and testers who need realistic test data quickly without learning a programming library or framework. The free tier covers basic needs, while paid plans scale to millions of records. The Enterprise tier adds private cloud hosting via Docker for teams that cannot send data to external services.
