Random Version 4
Generate standard 128-bit RFC 4122 Version 4 UUIDs using cryptographically secure random values (`crypto.getRandomValues`) to prevent predictability.
Bulk Generation
Create single values or generate batches of up to 500 unique identifiers simultaneously. Download output as a text file.
Client Privacy
Run all generation loop mechanisms inside local memory space. No values are logged, safeguarding backend transaction records.

UUID Version Matrix
| Version | Generation Basis | Collision Probability | Best Use Case |
|---|---|---|---|
| UUID v4 | Cryptographically secure random number sets | Virtually zero (1 in 2.71 x 10^37) | API database primary keys, session tokens, transaction logs. |
| UUID v7 | Timestamp epoch + random bits | Virtually zero | Time-ordered keys, relational database index optimization. |
| UUID v1 | Timestamp + network card hardware MAC address | Low (Requires unique MAC Address) | Legacy distributed systems tracking hardware origins. |
