UUID v4
Randomly generated using cryptographically secure randomness. Best for most use cases — database IDs, session tokens, file names.
⏱️
UUID v1
Time-based UUID. Encodes the current timestamp. Useful when you need sortable IDs. Our v1 uses a simulated timestamp (no real MAC address for privacy).
⬜
NIL UUID
All zeros: 00000000-0000-0000-0000-000000000000. Used as a null/placeholder value in APIs and databases that require a UUID format.
