Fake REST API Response Generator
Generate realistic fake JSON for mocking an API response.
Response fields
About this tool
Generates realistic-looking fake JSON — the kind a REST API might return — from a field list you define, for mocking an API response while building or testing a frontend before the real backend exists.
Everything is generated locally in your browser using built-in fake-data pools — nothing is uploaded, and no real API is called.
Frequently asked questions
- Is any of this real data?
- No — names, emails, and every other value are randomly assembled from generic word lists and don't correspond to real people.
- Can I control the exact shape of the response?
- Yes — add or remove fields, rename them, and pick each one's type; choose whether the output is a plain array of records or wrapped in a
{"data": [...]}envelope, a common REST API convention. - Is this uploaded or does it call a real API?
- No — everything is generated locally in your browser. Nothing is sent to any server.
