Frequently Asked Questions
What is the difference between UUID v4 and ULID?
UUID v4 is fully random, while ULID is time-sortable and encodes a timestamp, making it useful for ordered keys.
Are the generated UUIDs unique?
UUID v4 uses 122 random bits, making collisions astronomically unlikely for practical use.
Is generation done in the browser?
Yes, all identifiers are created locally in your browser, so nothing is sent to a server.
