UUID Generator

Generate unique identifiers (UUID v4) for your applications.

What is a UUID?

A UUID (Universally Unique Identifier), also known as a GUID (Globally Unique Identifier), is a 128-bit number used to uniquely identify information in computer systems. The key characteristic of a UUID is that it is "practically unique," meaning the probability of two independently generated UUIDs being the same is infinitesimally small.

This tool specifically generates Version 4 (v4) UUIDs, which are created using random or pseudo-random numbers. They are the most common type of UUID and are perfect for use cases like database keys, transaction IDs, session identifiers, and any scenario where you need a unique ID without relying on a central authority to issue it.
