Generate Version 4 UUIDs instantly for API keys, database IDs, and unique tokens.
A UUID (Universally Unique Identifier) is a 128‑bit value used to uniquely identify data. Version 4 UUIDs are generated using random numbers, making collisions extremely unlikely.
A typical UUID v4 looks like this:

Where x is a random hexadecimal digit and y is one of 8, 9, a, or b.
