UUID Generator
Random version-4 UUIDs, generated in your browser.
RFC 4122 version 4, properly formatted
Generates standard version-4 UUIDs — 128-bit identifiers with the version and variant bits set correctly per the RFC 4122 spec — the same format used across databases, APIs, and distributed systems where you need an identifier that's practically guaranteed not to collide with any other, generated anywhere, without coordinating with a central authority.
