Create UUIDs (GUIDs) for database keys, test data and APIs: random v4, or v7 that sorts by creation time.
Choose version 4 (random) or 7 (time-ordered).
Set how many you need and the format.
Copy them all, copy one, or download a text file.
v7 starts with a timestamp, so new IDs sort after old ones. That keeps database indexes compact, which is why it is a good choice for primary keys. v4 is fully random.
In practice no: a v4 UUID has 122 random bits. You would need to create billions per second for many years to expect a single duplicate.
Yes. Str::uuid() makes v4 and Str::uuid7() (Laravel 11+) makes v7; Eloquent's HasUuids trait uses ordered UUIDs.
