Use cases

Testing IDs

Create unique identifiers for QA records, local fixtures, and non-production datasets.

Database seeds

Fill seed data or migration examples with UUID-shaped values without reusing production identifiers.

API fixtures

Build request and response examples that need stable-looking UUID v4 values.

How it works

TempKit generates UUID v4 values on the server with Java UUID.randomUUID(), then formats them with your uppercase and hyphen preferences.
