Generate batches of UUIDs (v1 timestamp, v4 random, v7 sortable) using cryptographically secure randomness. Configurable count and casing.
This uuid generator runs 100% in your browser. Nothing you paste, drop, or generate ever leaves your device - no analytics on your input, no uploads, no logs.
v4 and v7 use crypto.getRandomValues.
