What UUID version does this generate?

It generates version 4 UUIDs, which are randomly generated and RFC 4122 compliant, the most common choice for general-purpose unique IDs.

Can two generated UUIDs collide?

The probability of a collision is astronomically small, which is why UUID v4 is trusted for database keys and distributed systems.

Can I generate multiple UUIDs at once?

Yes. Set the count you need and generate a batch in one click, ready to copy as a list.
