A deprecated JavaScript library for generating collision-resistant unique IDs optimized for horizontal scaling. It is insecure because it leaks timestamps and other information, and users should use its successor cuid2 instead.
Use cases
- generate unique ids for database records
- collision-resistant identifiers for horizontal scaling
- unique html element ids
- short random id generator for javascript
- migrate from cuid to cuid2
When to choose
- maintaining legacy code that already depends on cuid
- studying the original cuid id format and its security flaws
When to avoid
- starting any new project - it is deprecated and insecure
- generating ids that must not leak timestamps or be guessable
- security-sensitive use cases like password reset tokens or access-controlled resource ids
