UUID Generator vs UUIDGenerator.net
Both generate version-4 UUIDs for free. The difference is the source of randomness and where it runs: Gera Tools uses the browser's cryptographic random source (crypto.randomUUID / crypto.getRandomValues) entirely on your device.
Both are fine for generating UUIDs. Gera Tools generates them locally with the browser's cryptographic random source and no account — a clean, dependable choice.

FAQ
What UUID version does Gera Tools generate?
Version 4 (random) UUIDs, generated with the browser's cryptographically secure random source (crypto.randomUUID where available, otherwise crypto.getRandomValues).
Are the UUIDs generated locally?
Yes. Generation runs in your browser with no server call, so nothing is uploaded.
Can I generate many UUIDs at once?
Yes — you can generate a single UUID or a batch. UUIDGenerator.net also supports bulk generation if you prefer it.
