FAQ

How does Nano ID differ from UUID?

Nano IDs are usually shorter and support custom alphabets and lengths, which suits URLs and UI display. UUIDs have a fixed format and broader cross-system conventions.

Why is the default length 21?

21 is a common default with a low collision risk under the default alphabet. Adjust the length for your use case.
