About UUID v1 Generator
A UUID v1 is built from a 60-bit timestamp and a node ID, so values tend to be ordered by creation time. This is handy when you want a unique identifier that also roughly sorts by time.
Because it embeds a time component (and historically a MAC address), v1 is less ideal when privacy matters. For purely random IDs use v4; for a modern time-ordered option use v7.
FAQ
Is any data sent to a server?
No. UUID v1 Generator runs entirely in your browser — everything is generated locally and never uploaded to our servers.
