Stop hand-writing fake users, orders, and records every time you need to test an API, populate a database, or demo a UI. DataForge is a lightweight, zero-dependency tool that generates realistic-looking test data and exports it in exactly the format you need — JSON, CSV, SQL INSERT statements, or a Postman Collection with the data already saved as an example response.
Everything runs client-side in the browser. No server, no API keys, no external services, no data ever leaves the page — which also means installation takes under a minute: just upload three files, or open index.html directly.
KEY FEATURES:
19 built-in field types — name, email, phone, address, city, country, company, job title, birth date, created-at date, price, quantity, boolean, UUID, IP address, and more
4 export formats — JSON, CSV, SQL INSERT statements, and Postman Collection v2.1 (import straight into Postman with the example response pre-filled)
Save & load schemas — export your field configuration to a small .json file and reuse it instantly next time, or share it with teammates so everyone generates data with the same structure
Up to 5,000 records per generation
Zero dependencies — no npm install, no build step, no external libraries
Copy or download the result with one click
Fully client-side — nothing is sent to any server, safe for sensitive internal use
WHO THIS IS FOR:
Backend developers who need realistic seed data for a new database or API
QA / test engineers building fixtures for automated tests
Frontend developers who need mock JSON before the real API is ready
Anyone building a demo who needs a table or dashboard to not look empty
