User Agent Viewer
See your own browser's user-agent string and what it reveals about your setup.
What your browser is telling sites
Every site you visit receives your browser's user-agent string, and this shows you your own — the exact line your browser sends, broken down into the browser, version, operating system and device it reveals. It is a quick way to see what you are presenting to the web, useful when a site claims your browser is unsupported or you are debugging something device-specific.
Open it and your current user-agent is shown and explained.
Your digital fingerprint, in part
Your user-agent is one of the pieces of information that makes your browser identifiable, and seeing it is a small window into what sites can learn about your setup automatically. It differs from the other user-agent tools: a parser decodes any string you paste, a builder constructs a custom one, and this simply reports yours. If a site wrongly says your browser is out of date, checking your actual user-agent here confirms what you are really sending, which is often the first step in working out why a site is misbehaving for you specifically.

How is it different from a user-agent parser?
A parser decodes any string you paste; this reports the actual user-agent your browser is currently sending.
Is anything uploaded?
No. Your user-agent is read and shown in your browser only.
