About the Random UUID
The Random UUID creates RFC-style version 4 UUID identifiers. Each result is created when you request it rather than selected from a prepared list.
You control the result through the number of identifiers. The focused interface works without an account on mobile and desktop. UUIDs use random bytes with the standard version and variant bits applied.
Because the Random UUID runs in the browser-facing LuckyMe workflow, you can change the number of identifiers and create a fresh result immediately. Review important outputs before using them in a real decision, publication, import, or security-sensitive process. Random generation is useful for neutral sampling and realistic test data, but it does not replace professional judgement or validation for high-stakes work.
How to use it
- Open the Random UUID and review the default values shown in the form.
- Adjust the number of identifiers for the task you have in mind.
- Select Generate, review the output, and use Copy or Generate again when needed.
- Share the URL when someone else should open the same structured configuration.
Common uses
- Create database primary keys.
- Populate fixtures and API examples.
- Label distributed objects without coordination.
Frequently Asked Questions
Are UUIDs guaranteed never to collide?
No finite system can promise never, but collisions are extraordinarily unlikely.
Are these UUID version 4?
Yes. They follow the familiar lowercase UUID v4 layout.
Can I share the settings?
Yes. Supported structured settings are stored in the URL; the random result itself is not embedded in the link.
Can I create multiple results?
Yes. Generate a batch for test data or imports.
