Frequently Asked Questions
What version of UUID does this tool create?
It generates UUIDv4 (Version 4), which relies entirely on random numbers and is the industry standard for database keys and unique identifiers.
Is there any chance of generating a duplicate UUID?
The probability of a collision with UUIDv4 is practically zero. You would need to generate billions of UUIDs every second for decades to even risk a duplicate.
Can I generate UUIDs in bulk for database seeding?
Yes! You can instantly generate a large batch of unique IDs at once, perfect for testing environments and database migrations.
