About this tool
The UUID generator creates a random version 4 universally unique identifier in the standard lowercase format. Use a UUID as a database record key, an API request identifier, or a stable value in test fixtures. The result contains 32 hexadecimal characters and the usual hyphens. Generate a new value whenever you need an identifier without keeping a central counter.
