When to Use CUID2
CUID2 is a good choice for database primary keys when you need IDs that are safe
to expose in URLs, don't reveal creation order (unlike ULIDs), and are collision-resistant
across distributed systems. It's particularly popular in JavaScript/TypeScript projects
using Prisma ORM. For time-sortable IDs, consider ULID or UUID v7 instead.
