About API Mock Server Generator
Frontend development shouldn't wait for backend APIs. Our API Mock Server Generator creates instant mock REST API endpoints from your JSON data. Simply paste your sample JSON structure and get a working API endpoint you can use in your fetch calls, Axios requests, or any HTTP client. Perfect for prototyping user interfaces, testing frontend logic without backend dependencies, creating demos and presentations, and teaching API integration. The tool provides cURL and JavaScript fetch examples for easy integration. While this demo uses localStorage, it demonstrates the concept perfectly for development and testing scenarios.
