Frequently asked questions

Is the data really random?+

Yes — each generation uses Faker under the hood, so values change every run. Relations stay consistent within a single generation.

Can I use this for production seeds?+

Absolutely. The SQL export produces standard INSERT statements that work with Postgres, MySQL, and SQLite with minor tweaks.

How many rows can I generate?+

Up to 5,000 rows per table. Generation is instant for typical workloads since it runs locally.

Do you store my schema?+

No. Everything lives in your browser tab. Refresh and it's gone.
