FAQ

What version of UUID?

Version 4 — 122 bits of cryptographic randomness, collision odds are negligible.

Can I generate many at once?

Yes, bulk generation up to hundreds with one click.

Are these safe as database keys?

Widely used as such. For indexed columns at scale, consider ordered UUIDs to reduce page splits.
