How It Works
Select the UUID version (v4 random, or v1 time-based) and the number of UUIDs to generate. The tool uses crypto.getRandomValues for v4 to ensure each UUID is statistically unique, formats it with the standard 8-4-4-4-12 hyphenated layout, and lists all results in the output area.
Use Cases
