What is a CUID?

A CUID (Collision-resistant Unique Identifier) is a short, URL-safe, and highly unique string designed for horizontal scaling. CUIDs start with a "c", followed by a timestamp, a counter, a fingerprint of the client, and random data. This structure makes them very unlikely to collide, even across distributed systems. CUIDs are ideal for web applications and APIs where you need a compact, secure, and non-sequential ID that is easy to use in URLs.
