FAQ

What version of UUID does this generate?

No. UUIDs are generated in your browser and are not saved or uploaded by DevKitYard.

Yes. Use batch generation when you need many identifiers for test data or records.

Are UUID v4 values guaranteed unique?

UUID v4 values are designed to be extremely unlikely to collide, but no random identifier can be mathematically guaranteed unique.
