What is API Mock Generator?

API Mock Generator turns sample JSON into a practical starter artifact for API development. Generate mock API route definitions from sample JSON.

Generated output is meant to accelerate scaffolding. Review naming, optional fields, validation rules, and framework-specific annotations before production use.

FAQ

Is API Mock Generator production ready?

It is a starter generated from one sample. Review optional fields, exact numeric types, nullability, validation, and naming before shipping.

Does code generation run on a server?

No. JSONFather generates the output in your browser.

Can it handle nested JSON?

Yes. Nested objects and arrays are converted into nested model types where possible.
