Frequently asked questions
How is NanoID different from a UUID?＋
NanoID produces shorter, URL-safe IDs from a larger alphabet, giving similar collision resistance in fewer characters — handy for URLs and database keys.
Can I customise the length and alphabet?＋
Yes. Set any length and supply your own character set, for example digits only or an alphabet with no look-alike characters.
Are the IDs safe to put in URLs?＋
Yes — they're generated from the browser's secure random source and are URL-safe, though like any ID they aren't a substitute for a secret.
