The UUID Generator creates random UUID version 4 identifiers. A UUID is a long unique value developers use to label records, sessions, and items so no two clash, even across different systems.
How to generate a UUID
- Open the tool.
- Generate a new UUID.
- Generate more if you need a batch.
- Copy the values into your project.
Why developers use UUIDs
When you need a unique ID and cannot rely on a simple counter, a UUID fits perfectly. Because it is random and very large, the chance of two matching is tiny. This makes it safe for databases and APIs.
Handy for many tasks
Use UUIDs as primary keys, request IDs, or file names that must not repeat. They work well when data is created in many places at once, since each system can make its own without checking the others.
