Overview

Generate realistic mock JSON from any template, then publish it as a live, shareable REST API with full CRUD. Free & local.

⚡ Mock JSON Generator is the fastest way to create realistic fake JSON test data — and turn it into a live REST API in one click. 🚀 📝 Paste any JSON template and instantly generate 5 to 500 records. The generator automatically detects field types from your keys and sample values — names, emails, phone numbers, dates, image URLs, file links, booleans and numbers — and fills them with realistic random data. Nested objects and arrays are fully supported. ✨ 🌐 NEW — Publish a live, shareable API: Turn your mock data into a real, hosted REST endpoint with a single click. You get a public URL with full CRUD support (GET, POST, PUT, PATCH, DELETE) that works from your app, Postman, curl or fetch — perfect for building and testing a frontend before the real backend exists. 🔗 ✅ Features: 🎯 Generate realistic mock JSON from any template 🧠 Smart type detection: names, emails, phones, dates, images, files, booleans, numbers ⚡ Quick-add field buttons, one-click Format, and smart bracket auto-close 🔢 Choose record count (5–500) and wrap output as an array or object 📋 Copy to clipboard or 💾 download as a .json file 🌐 Publish a live REST API endpoint with full CRUD and a shareable URL 🗂️ Manage all your published endpoints from the Options page 🔒 Privacy: All data generation runs locally in your browser — nothing is tracked or collected. Publishing a live endpoint is optional and only uploads the data you explicitly choose to publish. 👩‍💻 Perfect for frontend and backend developers, QA engineers and designers who need realistic test data or a quick mock API for prototyping.
