How this works
Generated locally.
Nothing to license.
Every UUID on this page is generated in your browser using the Web Crypto API (crypto.getRandomValues), laid out according to RFC 9562. Nothing is sent to a server, logged, or stored: refresh the page and every value here is gone.
A random or time-based identifier is not a creative work, so there is no copyright or licence attached to the UUIDs this tool produces. Use them in any project, commercial or otherwise, with no attribution required.
* The UUIDs generated by this site are provided AS IS without warranty of any kind, not even the warranty that the generated UUIDs are actually unique. You are responsible for using the UUIDs and assume any risk inherent to using them. You are not permitted to use the UUIDs generated by this site if you do not agree to these terms. Do not use any UUIDs found on cached versions of this page.
