About UUIDs
Quick reference for developers
A UUID (Universally Unique Identifier) is a 128-bit identifier
designed to provide practical uniqueness across systems,
applications, and distributed environments.
UUID v4
Uses cryptographically secure random values for generating practically unique identifiers.
Standard Format
Standard UUIDs contain 32 hexadecimal characters separated into five groups by hyphens.
Browser-Based
UUID generation happens locally in your browser without sending generated values to a server.
