What is a UUID and why use one?
A UUID (Universally Unique Identifier) is a 128-bit value designed to be globally unique, which makes it ideal for database keys, distributed systems, and identifiers that must not collide across machines or environments.[web:183][web:186][web:193]
Common uses for UUID generators
- Generating IDs for database records, API resources, and microservices that cannot rely on incremental integers.[web:183][web:186]
- Creating anonymous identifiers for tracking, logs, or testing data without leaking personal information.[web:190][web:193]
- Quickly producing unique IDs while prototyping apps, scripts, and configuration files.[web:183][web:186]
