Details
A UUID (Universally Unique Identifier) is an identifier designed to be unique across the world. It is widely used for database primary keys, API request IDs, and file names where uniqueness matters.
This tool generates version 4 (random) UUIDs using cryptographically secure randomness, making collisions practically impossible.
Generate up to 1000 at a time, then copy or download them directly. Perfect for test data and development debugging.
