uuid

Paste a UUID to see what it carries: version, variant, and for time-based versions the exact timestamp, clock sequence and node. Also shows the raw bytes, the 128-bit integer and the URN form.

Generate UUIDs in versions 1, 3, 4, 5, 6 and 7, one at a time or in bulk. Pick a version, set how many you need, and regenerate with one click. Name-based versions take a namespace and a name, and the result copies as a plain list.
