Which UUID version does this tool generate?
It generates version 4 UUIDs, whose random fields come from the browser's cryptographically secure random-number facilities.
Are generated UUIDs saved?
No. Generated values remain in the current page and are not uploaded or stored by the site.
Can I generate deterministic UUIDs here?
No. This tool is intentionally limited to random UUID v4 values and does not implement name-based UUID versions.
