What UUID Generator does

Generate RFC 4122 v4 UUIDs in bulk, instantly. It runs entirely client-side, so nothing you enter is sent to a server — useful when working with sensitive data or when you just want an instant result without waiting on a network round-trip.

Common use cases

  • Seeding test data
  • Generating unique IDs for records

FAQ

Are these UUIDs cryptographically random?

Yes, generation uses the browser's crypto API, the same source used for v4 UUIDs elsewhere.
