UUID Generator

Generate random version-4 UUIDs (also called GUIDs) one at a time or in bulk. Set a count and produce a whole batch at once, then copy a single UUID or copy them all to the clipboard in one click - ideal for seeding databases, creating test fixtures, or assigning unique identifiers.

Each UUID is created with your browser's built-in cryptographic random generator, so the values are suitably unpredictable and conform to RFC 4122. The generator runs entirely client-side - nothing is requested from or sent to a server - which means it's fast, private, and works offline once the page has loaded. No signup, no limits beyond a sensible per-batch maximum.
