Frequently asked questions
Is this a v4 UUID generator?
Yes. It generates standard version 4 (random) UUIDs which are the most common type used for database primary keys and API tokens.
Are these UUIDs guaranteed to be unique?
Version 4 UUIDs have 122 random bits, making the probability of generating a duplicate virtually zero for all practical applications.
