What is a Nano ID?

Nano ID is a tiny, secure, URL-friendly unique-string generator. It uses a 64-symbol alphabet (A–Z, a–z, 0–9, plus _ and -), so a 21-character ID is shorter than a UUID while offering comparable collision resistance. This implementation uses crypto.getRandomValues() with bitmask rejection sampling for an unbiased distribution — all in your browser.
