What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit identifier commonly used to uniquely identify records, resources, sessions, requests, and other objects in software systems.

UUID v4

UUID version 4 is generated from random data. This tool uses the browser's cryptographically secure random UUID implementation when available, with a secure crypto.getRandomValues() fallback.

All generation happens locally in your browser. UUIDs are not sent to or stored on a server.
