A UUID (Universally Unique Identifier) is a 128-bit identifier standardised by RFC 4122 and formatted as five groups of hexadecimal digits separated by hyphens — for example 550e8400-e29b-41d4-a716-446655440000. Version 4 UUIDs are fully random, making them ideal for primary keys in distributed databases, correlation IDs in distributed tracing, and idempotency keys in payment APIs. This tool generates UUIDs using the browser's native crypto.randomUUID() — no server call required.
