Frequently asked questions
What is a UUID used for?
A UUID (universally unique identifier) is a 128-bit value used to uniquely identify database records, API objects, sessions, or files - without needing a central authority to guarantee uniqueness.
How likely is it that two generated UUIDs collide?
Astronomically unlikely - a standard v4 (random) UUID has so many possible values that generating billions of them still carries a negligible collision probability, which is why they're trusted for distributed systems.
Can I generate multiple UUIDs at once?
Yes - specify how many you need and generate a batch in one click.
