About this UUID generator
Generates version 4 UUIDs using your browser's crypto.randomUUID (falling back to crypto.getRandomValues), so the randomness is cryptographically strong — not Math.random. Generate up to 1,000 at a time and copy them as a newline-separated list.
IDs are generated on your machine and never logged, so they are safe to use as database keys, request IDs, or fixtures.
