API Mock Data Generator

Generate fake JSON for user lists, product lists, and more. Mock API responses for frontend development, testing, or demos. No backend needed—get realistic sample data instantly. User template includes id, name, email, username, avatar; product template includes id, name, price, category, stock.

How to Generate Mock JSON

  1. Select template: User list or Product list.
  2. Choose count (1 to 50 items).
  3. Click "Generate". Copy the JSON and use it in your app, Postman, or tests.

When to Use

Build UI before backend is ready, test pagination, create demo data, prototype APIs, or run frontend without a server. Data is random but realistic. Perfect for React, Vue, or any app that consumes JSON APIs. All in your browser.
