Skip to contentnanoid generates compact URL-friendly unique ids — smaller than UUID v4 with similar collision resistance.
nanoid uses a URL-safe alphabet (A-Za-z0-9_-) and default 21-character length, yielding ~149 bits of entropy — comparable to UUID v4 in a shorter string ideal for URLs and UI ids.
Unlike sequential integers, nanoids are hard to guess. Tentaco Nanoid Generator runs in your browser for bulk id creation during prototyping.
