How to use this tool well

Use this generator for database seed IDs, test records, request correlation IDs, local fixtures, and quick examples in API documentation.

Generate a fresh ID for each object that should remain distinct in logs or fixtures.
Use UUIDs for identifiers, not for secrets; they are unique labels, not authentication tokens.
When pasting into code, keep the same casing and hyphen layout expected by your system.
