UUID/ULID Generator

How to Generate UUIDs and ULIDs Locally on your Mac

Identifiers are everywhere in tests, fixtures, database rows and API examples. CodeSwissKnife generates UUIDs and ULIDs locally, including UUID v4, UUID v7 and ULID output.

Why generate identifiers locally?

Generated ids can be tied to test data, private fixtures or internal examples. Local generation avoids handing workflow context to a website.

Generate UUID v4, UUID v7 and ULID

Use random UUID v4 values, time-ordered UUID v7 values or ULIDs depending on the identifier format your system expects.

Use ids in tests and fixtures

Generate batches, copy results and use them with Mock Data Generator, JSON tools and API request examples.
