UUID Generator client-side ?
How to use UUID GeneratorA UUID (universally unique identifier) is a 128-bit value used to identify records, sessions or resources without risk of collision. This tool generates version 4 UUIDs, based on randomness, ready to paste into a database, code or configuration file.
The identifiers are produced locally in your browser from a secure random source. No generated value is sent to a server, so you keep full control over the identifiers you create.

Frequently asked questions
What is a v4 UUID?
It is a UUID where most bits are random. It is simple to generate and offers a negligible collision probability for most uses.
Can two UUIDs be identical?
It is theoretically possible but negligible in practice. The 122-bit random space makes a collision extremely unlikely.
Are the UUIDs generated online?
No. They are produced in your browser and are never transmitted to a server.
Is a UUID a secret?
No. A UUID is an identifier, not a password. It can be unique without being secret, so do not use it alone as a security token.
