Frequently Asked Questions
Is UUID the same as GUID?
Yes. UUID and GUID describe the same identifier format. GUID is commonly used in Microsoft ecosystems, while UUID is the standards-based term.
What kind of UUID does this tool generate?
It generates UUID v4, a randomly generated 128-bit identifier that is widely used for IDs in modern applications.
Can I use these UUIDs in production systems?
Yes. UUID v4 is suitable for most production use cases where globally unique IDs are needed, including API resources, database primary keys, and event IDs.
Are my UUIDs sent to a server?
No. UUIDs are generated locally in your browser using built-in Web APIs, so nothing is uploaded.
