Mock Data Generator

什麼是 Mock Data Generator？

A free, privacy-first mock data generator for developers that creates coherent, reproducible datasets. Generate data using a field picker, a pasted JSON sample, or JSON Schema. Emails, locations, and timestamps stay logically consistent. Use a seed for identical output every time. Export unlimited JSON, NDJSON, or CSV. Runs entirely client-side, works offline, and requires no signup.
