Customizable JSON mock API for testing REST endpoints

Visit Website

Overview

Mocky enables developers to create custom mock REST API endpoints with user-defined JSON responses. Users can configure HTTP status codes, headers, response content, and set expiration times for endpoints. It supports standard methods like GET, POST, PUT, and DELETE. Ideal use cases include testing front-end apps without backend dependencies, simulating error scenarios (e.g., 404, 500 statuses), validating API client data handling, and prototyping features. Responses are delivered in JSON format, and no authentication is required for basic endpoint creation.

Example Integration (JavaScript)

script.js JS

fetch('https://designer.mocky.io/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
