Chain this with other tools →NewHow it works
This tool generates UUIDs using the uuid library. UUID v4 creates random identifiers using cryptographically secure random numbers. UUID v7 creates time-sortable identifiers with a Unix timestamp prefix for better database performance.
Common Use Cases
- Generating unique identifiers for database records
- Creating session IDs or API keys
- Testing systems that require UUID inputs
- Generating correlation IDs for distributed tracing
Frequently Asked Questions
What's the difference between UUID v4 and v7?
v4 is purely random. v7 starts with a timestamp, making it sortable by creation time. v7 offers better database index performance.
Are UUIDs guaranteed unique?
Practically yes. With 122 random bits in v4, collision probability is astronomically low (billions of UUIDs before 50% collision chance).
