Tips and common questions
What is a user agent?
It is a short text your browser sends to every website saying which browser and system it is. Sites use it to adjust pages and count visitors.
Can a user agent be faked?
Yes. Browsers and bots can send any user agent, so treat it as a hint, not proof.
Where do I find user agents?
In your web server logs or analytics, or in the browser's developer tools under Network.
Privacy
Parsing happens entirely in your browser and even works offline. Nothing is uploaded.
