UUID v4 Generator

A Universally Unique Identifier (UUID) is a 128-bit label used for information in computer systems. This tool generates random UUIDs (Version 4).

Why Version 4?

UUID v4 is randomly generated. The probability of finding a duplicate (collision) is so small that it is effectively zero, making it safe to use for generating primary keys in databases, session IDs, or transaction tokens without checking for central coordination.
