Frequently Asked Questions

Is Mock Data Generator free?

Yes, it is completely free. All data generation happens locally in your browser using seeded pseudo-random algorithms — no server requests.

Is the generated data real?

No. All data is randomly generated from curated sample pools. Names, addresses, emails, and phone numbers are fictional and should only be used for testing and development purposes.

Can I reproduce the same data set?

Currently, each generation uses a time-based random seed, so data is different each time. For reproducible test data, consider using UUID or Number types with a fixed range.
