What is this?

This page generates Cuid2s for you to use in debugging, development, or anywhere else you may need a unique ID.

What Happened to the Original Cuid?

The author of Cuid has decided to deprecate the library in favor Cuid2. The reason for this is that Cuid is not cryptographically secure, while Cuid2 is.

Much care has but put into making sure that Cuid2 is a high quality replacement for Cuid or any other unique ID. For more information on those changes, see the Cuid2 repo.

Why use Cuid2?

Cuid2s are suitable for use in distributed systems where you need to generate unique IDs without a central authority.
