Frequently Asked Questions

  • What's the difference between UUID versions?

    V1 is time-based, V4 is fully random, and V7 is time-ordered random (newest, best for databases). V4 is the most commonly used.

  • Can I inspect existing UUIDs?

    Yes, paste any UUID into the inspector to see its version, variant, and timestamp (if applicable).
