How to see your browser’s user agent
- Open the page: your browser, operating system and engine are detected straight away.
- Scroll for screen size, language, time zone and other details.
- Click Copy to copy the full user-agent string, for example for a support request.
About this tool
Browser, OS, and engine are identified from the User-Agent string using the same kind of pattern matching most sites use, refined with the newer navigator.userAgentData Client Hints API where the browser supports it (currently Chromium-based browsers). Both approaches describe what the browser chooses to report, not a verified fact — any of it can be changed by browser settings, extensions, or developer tools, so treat this as informational rather than authoritative.
Everything else — screen size, language, timezone, touch support, CPU core count — comes directly from standard browser APIs (navigator, screen, Intl) with no parsing involved. Nothing detected here is sent anywhere; it's read and displayed entirely within your own browser tab.
Questions about user agents
What is a user agent?
A line of text your browser sends to every website, naming the browser, its version and your operating system.
Why do user agents mention Mozilla and Safari?
For historical compatibility: browsers copied each other’s names so websites would serve them the full version, so almost every user agent starts with Mozilla/5.0.
Can a user agent be faked?
Yes. Settings, extensions and developer tools can change it, so it’s informative rather than proof.
Is this information sent anywhere?
No. It’s read and shown in your browser only.
