What is a CUID?
CUID (Collision-Resistant Unique ID) is a format designed to be safe to generate in distributed systems. IDs are timestamp-prefixed (making them roughly sortable), URL-safe (lowercase alphanumeric), and opaque to prevent ID enumeration. CUID2 improves on the original by using a cryptographic hash for better uniqueness guarantees.
For UUID generation, use the UUID Generator. For ULID (timestamp-sortable like CUID), try ULID Generator. For NanoID, see NanoID Generator.
