As answered by people managing Codility and GUIDsGenerator.com.
GUIDsGenerator.com's answer:
Do it all online inside your browser for free. No API calls needed. No data sent anywhere. Just clean local performance and full RFC compliance.
GUIDsGenerator.com's answer:
A person should choose GUIDsGenerator.com because it goes beyond simple UUID generation and helps you understand what you’re using.
Most competitors only generate random UUIDs. GUIDsGenerator.com lets you generate, inspect, and analyze GUIDs and UUIDs in one place. You can instantly see the version, variant, timestamps, node information, and embedded structure for UUIDs v1–v8, with clear warnings and explanations when something matters for security or predictability.
On top of that, it includes a built-in wiki that explains GUIDs and UUIDs in plain language—what the different versions mean, when to use each one, and common pitfalls—so both developers and non-developers can make informed choices.
Everything runs fully in the browser, with no data sent to a server, making it fast, privacy-friendly, and safe to use.
In short: competitors generate IDs. GUIDsGenerator.com helps you generate them correctly, inspect them deeply, and understand them confidently.
