Frequently asked
Is this truly random?
Yes — uses crypto.getRandomValues(), which is cryptographically secure per Web Crypto spec.
Can I generate UUIDv7 (time-ordered)?
This tool generates v4 (random). v7 support is planned.
Why Is UUID v4 enough for most cases?
Collision probability is astronomically low (2^61 IDs before 50% birthday bound). Good for IDs that don't need ordering.
