How to use
Pick v4 (random) or v7 (time-ordered, great for database keys), choose how many, and copy the results.
Paste any UUID into the inspector to see its version, variant and — for v7 — when it was created.
FAQ
Is my data sent anywhere?
No. This tool runs entirely in your browser. Nothing you type, paste or upload is sent to a server or stored anywhere.
v4 or v7?
v4 is fully random. v7 starts with a timestamp, so new IDs sort after older ones, which keeps database indexes efficient.
Is a GUID the same as a UUID?
Yes — GUID is Microsoft’s name for the same 128-bit identifier.
