About UUID v4

UUID v4 is randomly generated using a cryptographically-secure random number generator. Each UUID contains 122 bits of randomness.

The probability of generating duplicate IDs is astronomically low — 1 in 5.3×10³⁶.

All UUIDs are generated entirely in your browser — nothing is sent to our servers.
