Frequently asked questions

Are these username values real?

No. Every value is randomly generated and 100% synthetic — safe to use in tests, demos, tutorials, and public examples.

Is the username generator free?

Yes — generate and download with no signup and no account.

What formats can I download?

CSV, JSON, SQL (CREATE + INSERT), or SQLite — and you can combine this field with others (names, dates, IDs, …) in the builder.
