What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is practically guaranteed to be unique across all space and time. Version 4 UUIDs are randomly generated and follow the format xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where y is one of 8, 9, a, or b.
How to use this tool
Set the number of UUIDs you want to generate (1 to 100) and click 'Generate'. Each UUID is displayed in standard format and can be copied individually or all at once. All generation happens in your browser using the crypto API.
Common use cases
Creating unique database record identifiers, generating session tokens and correlation IDs, assigning unique keys to distributed system components, and creating non-sequential identifiers for security purposes.
