FAQ

Does this UUID generator run locally in my browser?

Yes. UUIDs are generated in your browser (no server roundtrips required to create the IDs).

Which UUID version should I use (v1, v4, v7)?

Use v4 for random identifiers in most apps. Use v7 when you want sortable IDs (time-ordered) while keeping good randomness. Use v1 when you specifically need the legacy timestamp-based format (it can leak time and node information).

How many UUIDs can I generate at once?

You can generate single UUIDs or bulk-generate up to 500 UUIDs at a time and copy them in one click.
