Every time you visit a website, your browser automatically shares information about your device, browser, operating system, and network. This information is known as a User Agent and helps websites deliver compatible content and services.
The User Agent Finder allows you to instantly view the information your browser is sharing online and understand how websites identify your device.

A User Agent is a text string sent by your browser whenever you visit a website.
It contains details such as:
Browser name
Browser version
Operating system
Device type
Rendering engine
Websites use this information to display content correctly and optimize the user experience.
For example, a website may show a different layout on mobile devices compared to desktop computers based on the User Agent.
Most users never realize how much information their browser shares automatically.
Checking your User Agent can help you:
Verify browser details
Troubleshoot website compatibility issues
Test browser configurations
Analyze privacy exposure
Debug web applications
Understand device identification
Developers, security professionals, and privacy-conscious users frequently use User Agent tools for testing and analysis.

Anyone interested in understanding browser identity can benefit from using this tool.
Yes. Many browsers allow users to modify or spoof their User Agent using developer tools or browser extensions.
Not entirely. User Agent information is automatically shared with websites when you visit them.
Websites use User Agent details to ensure content is displayed correctly across different devices and browsers.
No. Private browsing typically does not hide User Agent information from websites.
Your browser shares more information than most people realize. Understanding your User Agent can help with troubleshooting, development, testing, and privacy awareness.
The User Agent Finder provides a quick and easy way to discover exactly how websites identify your browser and device.
Whether you're a developer, website owner, or simply curious about your browser's identity, this tool offers valuable insights in seconds.

Nice to know the UA string isn't what it used to be. Since Chrome rolled out User-Agent Reduction, the value here is basically a generic version/OS bucket for most people. The real device/browser details now mostly come from Client Hints headers (Sec-CH-UA-*) when a site requests them, not the UA string in this tool. That matters for privacy too: a bare UA string is pretty low-entropy on its own, it only becomes identifying when you add other passive signals like canvas or font enumeration, screen size, or IP/ASN, which is the fingerprinting vector. Still useful to keep the tool for the boring-but-real case: pasting your UA into a support ticket or bug report so a dev knows exactly what browser/OS combo you’re on. I’d be cautious about bundling ISP/ASN/geolocation with the UA as if that’s part of what your browser exposes, that’s mostly IP-based lookup on the server side, not the UA string itself, and merging the two overstates what a browser leaks.
Great point — thanks for highlighting that. You're absolutely right that modern browsers have reduced the amount of detail exposed in the traditional UA string, and Client Hints now carry much of that information. Also agree that IP/ISP/location data comes from separate network-level lookups, not the UA itself. I'll make that distinction clearer in the tool description to avoid conflating the two.
Wow, Ok, I don't want to understand how they do it, I just want to turn it off if possible.
Haha, fair enough 😄. You can't fully disable it, but you can limit what gets exposed with privacy-focused browsers and settings.
It's always surprising how much information a browser shares automatically.
A quick user agent check is a simple way to understand what websites can see about your device.
