Preguntas Frecuentes
What is a UUID?
A 128-bit identifier formatted as 32 hex digits in five groups separated by hyphens. Version 4 UUIDs are randomly generated with near-zero collision probability.
Are generated UUIDs truly unique?
Version 4 uses 122 random bits producing over 5 undecillion possible values. You would need 1 billion per second for 85 years for a 50% collision chance.
Can I use UUIDs as database primary keys?
Yes. UUIDs allow distributed ID generation without coordination. They use more storage than integers and may cause index fragmentation in some databases.
Todos los UUIDs se generan localmente en tu navegador usando crypto.getRandomValues(). Ningun dato se envia a servidores.
