What is NanoID?

A short, URL-safe random ID. The default alphabet has 64 symbols (A-Za-z0-9_-) and the default length is 21 — that's ≈126 bits of entropy, comparable to a UUIDv4 in less space and without dashes.

Picking a length

Use the collision-probability estimate to size the ID for your volume. For 1 billion IDs at the default alphabet, 21 characters keeps collision risk below one in a trillion.
