How to use this tool

Create random UUID v4 identifiers for test fixtures, records or application prototypes. Each run uses the server's cryptographic UUID generator and returns one identifier per line.

  1. Enter how many UUIDs you need, from 1 to 100.
  2. Run the generator.
  3. Copy the list or download the text result for your project.

Example to try

Count: 5 produces five UUID v4 identifiers, one per line.

Supported use and limits

Only random version 4 UUIDs are generated. Name-based UUIDs and time-ordered UUID versions are not supported. Use database uniqueness constraints where your application requires them.

Can I reproduce a UUID from the same input?

No. This generator creates new random identifiers on each run. It does not take a namespace or name for deterministic UUID generation.

Free to use without an account. Submitted input is processed on our server. How Sarvam Tools works.
