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.
