FAQ
Can UUIDs be duplicated?
The probability is extremely low (~2^-122). In practice, UUIDs can be considered unique.
What's the difference between UUID v4 and v1?
v4 is fully random; v1 is based on timestamp and MAC address. This tool generates the most common v4.
Can multiple UUIDs be generated at once?
Yes. Batch generation of multiple UUIDs is supported for convenience.
