UUID Generator creates unique identifiers (Universally Unique Identifiers) typically used for database keys, session tokens, or other random labels that must not collide. Each UUID is a 128-bit number often represented in hex, like 123e4567-e89b-12d3-a456-426655440000. You can safely assign these without worrying about duplication across systems. They’re helpful for distributed architectures, ensuring distinct IDs even if multiple nodes generate them. For SEO or user-facing scenarios, they can be used to obfuscate internal IDs or track referral codes. Essentially, the UUID Generator is a quick, reliable way to produce globally unique references.
