UUID TOOL
Generate random UUID v4 values for development.
Create one or a small batch of UUIDs for test fixtures, mock API responses, database seeds, and local development. Values are generated on your device and can be copied as a newline-separated list.
What is a UUID v4?
A UUID is a 128-bit identifier commonly written as five groups of hexadecimal characters. Version 4 values are generated from random data and include a version marker in the third group.
When to use generated UUIDs
- Creating local test data that should not collide with existing IDs.
- Building a mock request or response before an API is ready.
- Filling a development database without using real customer identifiers.
Do not use a client-side demo generator as a substitute for a server-side identity strategy, authentication secret, or security token.
