How it works

Generate UUID v4 or v7 values locally, one at a time or in bulk.

Use it to create one or more local identifiers for fixtures, records, or prototypes.

Example

Generate three time-ordered UUID v7 values for local test records.

Notes

  • v4 is fully random. v7 is time-ordered and easier to sort chronologically.
  • Bulk output is generated locally in the browser.
  • Count is intentionally capped to keep the UI quick and readable.

Constraints

  • Generates UUID v4 or v7 values only, using browser cryptographic randomness.
  • Limit: 50 UUIDs per action. Nothing is uploaded or silently truncated.

Common errors

  • Count outside bounds
  • Unsupported secure randomness
  • Expecting database uniqueness checks

When to use it

Use it to create one or more local identifiers for fixtures, records, or prototypes.

Formats: UUID v4, UUID v7, 1–50 values.
