QUICK ANSWER
What is a test data generator?
A test data generator creates fictional records that imitate the shape of production data without copying real customers. MockDataKit lets developers choose fields, locale, quantity, and a seed, then reuse the same safe dataset across UI tests, database seeding, demos, and API fixtures.
- Output formats
- Table, JSON, CSV, and executable SQL
- Available fields
- Identity, contact, address, internet, employment, and safe finance display values
- Generation limit
- Up to 1,000 browser-generated records per run
- Privacy model
- No signup and no generated records uploaded to MockDataKit
BUILT FOR THE TIRED PART OF DEVELOPMENT
Useful data without privacy anxiety
Get realistic records without creating accounts, finding API keys, or exposing anyone’s personal information.
Generate locally
Your browser creates synthetic records without sending them to a server.
Ship your test
Copy or download clean Table, JSON, CSV, or SQL output.
PRACTICAL WORKFLOWS
Where developers use synthetic test data
Start with the output your workflow already expects, then keep the seed with your test so failures are easier to reproduce.
Frontend and end-to-end tests
Fill registration, profile, checkout, and admin screens with realistic names, dates, addresses, and account states.

QUICK ANSWERS
About your generated data
Is this real personal data?
No. MockDataKit generates fictional records intended only for development and testing.
Does the data leave my device?
No. This first version runs entirely inside your browser.
Can I reproduce the same records?
Yes. Enter the same seed, field selection, quantity, and age range.
Can I use it for production customers?
No. Use generated records for testing, demos, QA, and development—not as verified identities.
