Why use an online UUID generator?

Most programming languages have a simple way to generate UUIDs. But, sometimes you might just need a single UUID and do not want to write any code.

Additionally, we try to make these tools intuitive and explain the differences between the different UUID versions. Testing out the UUID generator above and the UUID decoder will give you a good idea of how UUIDs work and which version to use in your own project or application.
