Cryptographically random (crypto.randomUUID)

Batch 1-100 at once

Copy individual or all

Standard 8-4-4-4-12 hex format

No upload, no logging

Built differently

Why the UUID Generator is different

Browser-native

The UUID Generator runs entirely in your browser. Input is processed locally — never uploaded, never logged, never cached anywhere outside your device.

No artificial limits

No daily quotas, no character ceilings, no "upgrade for more" walls. Every feature is the complete feature — the same on the first use as the thousandth.

Production-grade quality

Built to the same engineering bar as paid SaaS tools — accurate algorithms, audited logic, responsive design and accessibility-tested interactions.

Use Contexts

Common use contexts

  • Database primary keys
  • API request IDs
  • Session tokens
  • Distributed system entity IDs
  • Test data seeding
Privacy by design

Private and secure

Zero upload

All processing happens in your browser. Input is never transmitted, logged or cached.

Works offline

Once the page loads, the tool runs without an internet connection. No network calls happen during use.

No tracking

No accounts, no cookies for tool state. Only aggregate analytics count visits at the page level.
