FAQ
How many UUIDs can I generate at once?
This version caps the batch size to keep the tool responsive, which is more than enough for most frontend and QA workflows.
Do I need a server for this?
No. The browser can generate UUIDs locally, which keeps the workflow fast and simple.
How it works
Create multiple UUIDs at once in the browser and copy a clean list for development, QA, and content demos. The result is produced immediately so you can review it before copying or using it elsewhere.
Privacy
The tool is designed to process ordinary input in your browser. Avoid pasting passwords, private keys, access tokens, personal records, or other sensitive production data into any online utility.
Limitations
This utility handles the focused workflow described on this page. Check the result before production use, especially when an input depends on a vendor-specific format, security rule, or external standard.
