UUID Generator FAQ
Which UUID version should I use?
Use v4 when you need a random identifier, v1 when a timestamp-based UUID is required, and v7 when you want time-ordered identifiers for database-friendly sorting.
Can I generate multiple UUIDs at once?
Yes. Choose a quantity from the menu to generate up to 100 UUIDs, then copy or download the result.
Are generated UUIDs sent to a server?
No. UUIDs are generated locally in your browser and are not uploaded or stored by DevKit.
