Frequently asked questions
Is the data real?
No — it's randomly generated fake data, safe to use for testing without exposing real people.
Is it free?
Yes — it is free with no sign-up, no watermark and no account-based quota. Your browser, device memory and the bench's stated file limits still determine how much it can process at once.
