About UUIDs
UUID v4 (Random)
The most commonly used version. Generated using random numbers, providing 122 bits of randomness. Collision probability is extremely low (1 in 5.3×10³⁶).
UUID v1 (Time-based)
Generated using timestamp and MAC address. Useful when you need sortable IDs or want to extract creation time.
Short ID
A 22-character alphanumeric string. More compact than standard UUIDs while still providing sufficient uniqueness for most applications.
Use Cases
Database primary keys, session tokens, file names, API identifiers, tracking codes, and any scenario requiring unique identifiers.
