Generate up to 1,000,000 records of realistic JSON, CSV, or SQL data instantly—no signup, no rate limits, and 100% free. Perfect for testing, prototyping, and load-testing.

Hi Product Hunt! 👋 I built JSONForge because I was tired of the "friction" in current mock data tools. Most generators either require a signup just to export a file, have restrictive rate limits, or send your proprietary schema data to their cloud servers. I wanted something different: Zero Drama: No accounts, no emails, no "Pro" paywalls. Total Privacy: Everything runs 100% in your browser. Your data stays on your machine. Massive Scale: Generate up to 1 million records in seconds using your local CPU power. Whether you're a frontend dev needing realistic user profiles or a backend engineer load-testing a database, I hope JSONForge saves you some time today. I’ll be here all day to answer your questions and hear your feedback! Muhammad Usaid Javaid
