Why use this UUID generator?
- Start with v7 by default for modern time-ordered IDs.
- Switch to v4 quickly when you need purely random UUIDs.
- Use v5 for deterministic UUIDs from a namespace and seed.
If you are working in C#/.NET naming conventions, try the dedicated GUID Generator.
How to use
- Choose a UUID version in the dropdown.
- Set count and optional format toggles.
- Click Generate, then copy or download the results.
