## FAQ

### What is the difference between v4 and v7?

v4 is fully random. v7 includes a timestamp prefix for sortable, time-ordered identifiers.

### Can I generate UUIDs in bulk?

Yes. Generate up to 1,000 UUIDs at once and copy or download the list.

### Is it safe to paste production data?

Yes. UUIDs are generated locally via the Web Crypto API. None of the generated values are logged or cached server-side, which matters when you generate IDs that will be used in production immediately.
