- Enter the number of UUIDs to generate.
- Click 'Generate' to instantly create UUIDs.
- Click on a generated UUID to copy it.
Key Features
- UUID v4 (random-based) generation
- Batch generation of multiple UUIDs at once
- One-click copy functionality
- Cryptographically secure random number generation in browser
Tips

Frequently Asked Questions
Probabilità collisione UUID v4?▼
Con 122 bit casuali servirebbero ~2,71×10^18 UUID. Praticamente impossibile.
Differenza v1, v4, v7?▼
v1: timestamp+MAC. v4: casuale puro. v7: timestamp+casuale, ideale per chiavi DB.
UUID o auto-increment?▼
UUID per sistemi distribuiti. Auto-increment per DB singolo. v7 buon compromesso.
