Nano ID Generator

The Nano ID Generator creates compact, URL-safe random identifiers using the default Nano ID alphabet (A-Z, a-z, 0-9, _ and -), with a length slider from 4 to 64. You can supply your own alphabet or generate up to 1000 IDs in one go.

Nano IDs are popular for database keys and short-lived tokens where UUID length is overkill. IDs are produced with the browser’s cryptographically secure random source when available. Everything runs locally.
