About this tool
Generate identifiers in bulk: UUID v4 (random), UUID v7 (time-ordered, sortable, RFC 9562), ULID (Crockford base32, lexicographically sortable) and nanoid (compact, URL-safe). Copy the whole batch in one click.
All randomness comes from crypto.getRandomValues, not Math.random, so the output is suitable for identifiers that must be unpredictable.
