How to use this tool

Create one or many random UUID v4 identifiers for test data, database records, fixtures, and prototypes.

Steps

  1. Choose how many UUIDs to generate and whether to keep hyphens.
  2. Select lowercase or uppercase output, then generate a fresh batch.
  3. Copy the values or export the complete batch as a TXT file.

Generate identifiers locally

UUIDs are commonly used when a project needs unique-looking identifiers without coordinating with a central database first.
