Mockaroo

Mockaroo is a hosted test-data generator with configurable schemas, browser downloads, APIs, mock API routes, datasets, and de-identification. Output formats and row or request limits depend on the selected workflow and plan. 1

Manufacturer / project: Mockaroo

When does it fit?

Best for developers who want schema-driven sample files or mock API responses without building a generator, and can work within hosted-service plans. 1 · 2

Fit still depends on your mandatory requirements.

What should you check before choosing?

Free browser files are capped at 1,000 rows and the free generation API at 200 requests per day. Bulk capacity, API records, and private deployment depend on paid plans. 1 · 2 · 3

What must your PoC prove?

Use a parent/child fixture, one invalid row and a fixed expected result. Check cleanup after failure, restore the configuration and repeat with pinned inputs. Unresolved requirements need a demonstration.

Acceptance plan, not a product test result. Execution scope and limits.

Deployment and license

Hosted at mockaroo.com for Free, Silver, and Gold; Enterprise is distributed as a Docker image for a private cloud or datacenter. 1 · 2 · 3

Commercial hosted service with free and paid plans; no open-source software license for the service is stated in the reviewed primary sources. 1 · 2 · 3

Confirm the entitled version and operating requirements.

How you work with it

Define a schema in the hosted service and download data or use mock APIs. Enterprise supports a private Docker deployment. 1 · 2 · 3
