Frequently asked questions
▸Which UUID version do I get?
Version 4 — random UUIDs, the most widely used type for database keys and request IDs. Each one contains 122 random bits.
▸Can two UUIDs ever collide?
Practically never. With 122 random bits you'd need to generate billions per second for ages to see a single collision.
▸Can I generate a big list at once?
Yes, produce hundreds in one click and copy them all. Everything runs locally — free, no account needed.
