UUID Generator

Generate UUID v4 values in bulk for fixtures, traces, and test data.

Input / Output

Start with the tool

Input, output, and copy actions stay in this main surface. Examples and reference checks are separated below.

Copy-ready output

Input state is saved only in this browser so you can restore the last workspace without an account.

Review after the result

Open examples, checks, and related tools only after the primary input/output flow is done.

Generate a secure token

Create random session/API/CSRF values, copy a safe token report, compare hashes, and choose identifiers deliberately.

3 Tools
  1. 1. Token

    Generate URL-safe session, API, CSRF, or webhook tokens and copy a report without exposing the token value.

  2. 2. Hash

    Compare digest or HMAC output for signatures.

  3. 3. UUID

    Use UUIDs for identifiers, not as secrets.

Before copying

  • Choose the count you need and keep one UUID per line when copying bulk output.
  • Use random tokens instead when the value must behave like a secret.
  • Confirm the target system accepts lowercase UUID v4 format.

Common failure cases

  • UUID v4 values are unique identifiers, not secrets or sortable timestamps.
  • Fixture data can accidentally reuse copied IDs if bulk output is edited manually.
  • Choose the count you need and keep one UUID per line when copying bulk output.
  • Use random tokens instead when the value must behave like a secret.
  • Confirm the target system accepts lowercase UUID v4 format.
