Questions

Is it really free?

Yes, up to a size. Every dataset's first 20,000 rows are free in the web app, and so is designing the schema, however large. A dataset bigger than that is metered in credits for the rows past the allowance, and the job quotes its cost before it runs.

Is the allowance per month?

No. It is per dataset. Every dataset you generate gets its own first 20,000 rows free, so there is no monthly quota to run out of.

Do I need a credit card?

No. You need an account to generate, but not a card. You only buy credits if a dataset outgrows the free rows or you automate with an API key.
