UUID Generator
Mint version-4 UUIDs from your browser's cryptographic generator. Grab one, or a whole batch, and switch to uppercase or dash-free formats as you need.
How it works
Each identifier is a version-4 UUID, meaning it is essentially all random bits with a couple reserved to mark the version and variant. The randomness comes from your browser's cryptographic generator, not a predictable pseudo-random source, so collisions are astronomically unlikely even across large batches. Toggle uppercase or the dash-free form to match whatever your database or API expects.
