About the My User Agent
The user agent is a single line your browser sends with every request. It has accumulated decades of compatibility fiction - every browser claims to be Mozilla, and Chromium-based browsers claim to be several engines at once.
Copy it when a support request asks for your browser details, or when testing how a server responds to different clients.
Questions people ask
Is any of this information sent anywhere?
No. Every value is read from your browser by JavaScript running in this page and displayed locally. Nothing is transmitted, logged or stored.
Is it free, and do I need an account?
Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
