Cuid2 is a JavaScript library and CLI for generating secure, collision-resistant unique identifiers optimized for horizontal scaling and performance. It uses multiple independent entropy sources hashed with SHA-3 to produce URL-friendly IDs without coordination between machines.

Use cases

• generate unique ids for database records
• replace uuids with collision-resistant ids
• generate ids across multiple servers without coordination
• create url-friendly unique identifiers
• generate unique ids offline without a network
• generate ids from the command line

When to choose

• you need secure, non-guessable unique ids in a distributed or horizontally scaled system
• you want url-safe ids without special characters
• you need offline id generation with no coordination service

When to avoid

• you need sequential or k-sortable ids
• you need maximum speed in tight loops like render loops where security and cross-host uniqueness are not required
