ID Generator
Generate UUID v4, ULID, or Nano ID — all cryptographically random, all client-side.
What is the UUID/ULID Generator?
The UUID Generator creates massively collision-resistant unique identifiers locally, utilizing the browser's high-entropy cryptographic generator.
UUIDs are the backbone of primary keys in distributed databases. Since this runs completely client-side, bulk generating thousands of keys is instant and untraceable.
Frequently Asked Questions
What does UUID stand for?
Universally Unique Identifier. It is a 128-bit label mathematically guaranteed to be incredibly unique without relying on a central database checking for existing IDs.
What is a ULID?
Universally Unique Lexicographically Sortable Identifier. ULIDs encode the timestamp natively, allowing database indices to sort them by creation time. The first 10 characters encode millisecond precision time.
What is Nano ID?
A tiny, URL-safe unique string generator. At 21 characters (default), Nano ID has the same collision probability as UUID v4 but is shorter and uses only URL-friendly characters.
How unlikely is a UUID collision?
Extremely unlikely. With 340 undecillion possible combinations, you would need to generate 1 billion UUIDs per second for 85 years to hit a 50% chance of a collision.
Does a server see these keys?
Never. By utilizing `crypto.randomUUID()` and `crypto.getRandomValues()`, the OS guarantees cryptographic randomness exclusively on the client machine.
