UUID Generator

Why Generate UUIDs?

Universally Unique Identifiers (UUIDs) are 128-bit values used as primary keys, session tokens, correlation IDs, and more. Version 4 UUIDs are generated from cryptographically secure random numbers, making collisions effectively impossible. Our generator uses the native crypto.randomUUID() API for maximum entropy and speed.

Features

  • Batch generation — create 1 to 100 UUIDs in a single click.
  • Crypto-secure — powered by the browser's native crypto.randomUUID().
  • Copy individual — click any UUID to copy it to the clipboard.
  • Copy all — grab every UUID at once, separated by newlines.
  • Regenerate — get a fresh batch without reloading the page.

Common Use Cases

  • Generating primary keys for database rows without a central sequence.
  • Creating unique session or request IDs for distributed systems.
  • Seeding test data with realistic-looking identifiers.
  • Producing correlation IDs for tracing requests across microservices.
