Hash IDs vs UUID
Developers should use Hash IDs when they need to expose database IDs in public interfaces like URLs or API responses without revealing the underlying sequential nature or scale of the data meets developers should use uuids when they need to generate unique identifiers across distributed systems or independent components without a central authority, such as in microservices architectures, database primary keys, or file naming. Here's our take.
Hash IDs
Developers should use Hash IDs when they need to expose database IDs in public interfaces like URLs or API responses without revealing the underlying sequential nature or scale of the data
Hash IDs
Nice PickDevelopers should use Hash IDs when they need to expose database IDs in public interfaces like URLs or API responses without revealing the underlying sequential nature or scale of the data
Pros
- +Common use cases include e-commerce product pages, user profile links, or any scenario where hiding the actual database row count or preventing ID enumeration is important for security or privacy
- +Related to: hashing-algorithms, url-design
Cons
- -Specific tradeoffs depend on your use case
UUID
Developers should use UUIDs when they need to generate unique identifiers across distributed systems or independent components without a central authority, such as in microservices architectures, database primary keys, or file naming
Pros
- +They are particularly valuable for avoiding collisions in large-scale applications, ensuring data integrity in replication scenarios, and simplifying ID generation in offline or disconnected environments
- +Related to: database-design, distributed-systems
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Hash IDs if: You want common use cases include e-commerce product pages, user profile links, or any scenario where hiding the actual database row count or preventing id enumeration is important for security or privacy and can live with specific tradeoffs depend on your use case.
Use UUID if: You prioritize they are particularly valuable for avoiding collisions in large-scale applications, ensuring data integrity in replication scenarios, and simplifying id generation in offline or disconnected environments over what Hash IDs offers.
