Generating UUIDs: frequently asked questions
Straight answers to the questions people ask most.
Is it really free?
Yes. There is no paywall, no trial, no watermark, and no usage cap. Open UUID and use it as often as you like.
Does it store or upload my data?
No. Everything runs locally in your browser, and generated UUIDs aren't stored or sent anywhere.
Do I need to install anything?
No installation, no plugins, no extensions. A current browser is all you need.
What's the difference between v4 and v7?
v4 is random; v7 is time-ordered and sorts chronologically.
Can I generate several at once?
Yes. Set a count to generate a batch and copy them all at once.
Does it work on my phone?
Yes. The tool adapts to any screen, so it works on phones, tablets, laptops, and desktops.
Verdict
Generating UUIDs is free, private, unlimited, and cross-device. Start at UUID.
