Frequently asked questions
v4 or v7?
v4 is fully random. v7 starts with a timestamp, so new IDs sort after older ones, which keeps database indexes efficient.
Can two UUIDs collide?
Practically never: v4 has 122 random bits.
Is my data sent anywhere?
No. Everything runs in your browser; nothing is uploaded.
