UUID generator

One identifier or a thousand, made locally.

Generate random version 4 UUIDs for fixtures, prototypes, database records, and distributed systems without a network request.

Maximum 1,000 per batch.

When is a UUID useful?

A UUID is convenient when many systems need to create identifiers without coordinating an incrementing counter. It is not a secret, access token, or proof of identity; use the password generator when unpredictability is itself the security control.
