Practical usage guide
Generate UUID values for testing, payloads, APIs, integration messages and development scenarios.
Select Generate UUID to create a random UUIDv4 using Web Crypto. Each action produces one new identifier.
Check the UUIDv4 structure: xxxxxxxx-xxxx-4xxx-[89ab]xxx-xxxxxxxxxxxx. The brackets indicate the permitted variant character, not literal brackets in a UUID.
Use the IDs where UUIDv4 is accepted. They encode neither content nor order, and generating one does not reserve it in a database.
