About the UUID tool
Generate one or many RFC 4122 version-4 UUIDs using the browser’s secure random source. Copy the whole list or an individual ID with a click.
v4 UUIDs contain 122 random bits; collision odds are negligible for realistic use. For database primary keys consider whether you also want time-ordered IDs.
Everything runs locally in your browser: no data is uploaded, no account is needed, and it works offline once the page has loaded.
