UUID (Universally Unique Identifier) is a 128-bit identifier guaranteed to be unique across all computers and time. Used in databases, APIs, and distributed systems.

What is the difference between UUID v1 and v4?

UUID v1 is time-based and includes the machine's MAC address. UUID v4 is completely random and more widely used for security reasons.

Can I generate multiple UUIDs at once?

Yes! Generate up to 1000 UUIDs at once in bulk mode.
