About This Tool
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier designed to be unique across all devices and time. They look like this: 123e4567-e89b-12d3-a456-426614174000
UUIDs are perfect when you need an ID that won't collide with other IDs, even if they're created on different systems without coordination.
Types of UUIDs
Our tool supports multiple types of unique IDs:
- UUID v1: Time-based (includes timestamp and computer ID)
- UUID v4: Random (the most common type, completely random)
- UUID v7: Modern time-ordered ID (good for databases)
- GUID: Microsoft's version of UUID
- And more: ULID, XID, NanoID, MongoDB ObjectID, CUID, etc.
Common Uses
- Database primary keys
- Session IDs for web apps
- Unique filenames
- Transaction IDs
- Tracking objects across systems
