Technical Guide

How the Mock API Generator Works

The Mock-Lab Mock API Generator is a client-side tool that simulates a backend server directly in your browser. It allows you to design APIs, generate random data, and test edge cases without writing backend code.

Define Your Schema

Paste a JSON object representing your desired data structure. The generator automatically detects fields and types.

Configure Behavior

Set custom status codes (200, 404, 500) and artificial latency to test loading states and error handling in your frontend.

Use the Endpoints

We generate a unique URL for your workspace. Use these endpoints in your frontend fetch calls just like a real API.
