Press Generate, then Copy all or Download.

Use Cases

Creating one record by hand in a database GUI.

Frequently Asked Questions

Can I generate one UUID without JavaScript enabled?

The generator runs locally in your browser, so JavaScript is required. Any of the one-line code samples above does the same job in a terminal or script.

Which version is generated by default?

v4 (random). Switch the version selector for v1, v3, v5, v6, v7, or v8.
