About UUID generator

A UUID (Universally Unique Identifier) is a 128-bit label used to uniquely identify objects in computer systems without central coordination. Version 4 UUIDs are generated from random or pseudo-random numbers and have a theoretical collision probability so low they can be treated as practically unique in any real-world system. The UUID Generator creates cryptographically random v4 UUIDs using the browser's native `crypto.randomUUID()` API, with bulk generation support for database seeding, test fixture creation, and anywhere unique identifiers are needed at volume.
