API Mock Generator
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.
How to use API Mock Generator
Paste a representative JSON payload and run API Mock Generator. Copy the generated model, struct, class, dataclass, or mock definition into your codebase, then refine it for your project conventions.

}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.
