Frequently asked questions
Is a GUID the same as a UUID?
Yes. GUID is Microsoft's name for a UUID. Guid.NewGuid() in .NET produces a version 4 UUID.
Is the GUID Generator free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Is the output random every time?
Yes. Values are generated fresh on each run in your browser; nothing is stored, so copy or download what you need.
