What is a UUID and what is it used for?

UUID (Universally Unique Identifier) is a 128-bit label used to uniquely identify objects in computer systems. Common uses include database primary keys, session tokens, API resource identifiers, and distributed system IDs.

What is the difference between UUID v1 and UUID v4?

UUID v1 is generated using the current timestamp and the host machine's MAC address, making it time-ordered. UUID v4 is generated using random numbers and is the most commonly used version for general-purpose unique identifiers.

Can I generate multiple UUIDs at once?

Yes. The UUID Generator lets you specify a bulk count and generates up to hundreds of UUIDs at once. You can copy them all to the clipboard with one click.
