What Is My Browser

What is What Is My Browser?

What Is My Browser is an online tool that automatically detects and displays information about your web browser and device. When you visit the tool, it reads your browser's user agent string and other request headers to identify your browser name and version, operating system, device type (Desktop, Tablet, or Mobile), screen resolution, and language preferences. No input is required; the tool detects everything automatically. It is useful for troubleshooting compatibility issues, verifying that a site detects your device correctly, and for developers and support staff who need to know a user's browser environment.

Websites and web applications often need to adapt their behavior based on the visitor's browser and device. A site may serve a mobile layout to phones and a desktop layout to computers. It may warn users on outdated browsers to upgrade. Support teams ask users for their browser information when debugging issues. What Is My Browser provides this information instantly by analyzing the HTTP headers sent with each request. The user agent string, in particular, contains encoded information about the browser, rendering engine, and operating system.

The tool presents the information in a clear, readable format. Instead of showing the raw user agent string (which can be long and cryptic), it parses and displays human-readable values: "Chrome 120 on Windows 10" or "Safari 17 on iPhone". It also shows device type, which helps users and support staff quickly identify whether the visitor is on a phone, tablet, or desktop. Language and locale information helps with internationalization and localization support.

Developers use What Is My Browser to test how their sites detect different browsers and devices. Support teams use it to gather environment information from users reporting bugs. End users use it to check what their browser reports before contacting support or when troubleshooting why a site behaves differently on their device. The tool is free, requires no signup, and works on any device with a web browser.

Who Benefits from This Tool

Web developers and QA engineers use it to verify browser detection logic. When building responsive or adaptive sites, developers need to ensure that device and browser detection works correctly. Visiting the tool from different browsers and devices confirms what the server receives. It also helps when debugging issues that occur only in specific browsers.

Support and help desk staff use it when users report problems. Instead of asking users to find their browser version in settings (which can be confusing), support can direct them to What Is My Browser. The user visits the page, and the displayed information can be copied or shared. This streamlines troubleshooting and ensures accurate environment details.

End users benefit when they need to report their browser information for compatibility checks, software support, or when a site asks them to upgrade. The tool provides a one-click way to see what their browser reports without navigating through browser settings.

Digital marketers and analysts sometimes use it to verify tracking or analytics setup. Ensuring that device and browser detection works correctly helps with segmentation and reporting.

Key Features

Automatic Detection

The tool requires no user input. Simply visiting the page triggers detection. The browser automatically sends headers with each request; the tool parses and displays them. This makes it fast and easy for non-technical users.

Browser Name and Version

The tool identifies the browser (Chrome, Firefox, Safari, Edge, etc.) and its version number. Version information is critical for compatibility; some features or bugs apply only to specific versions.

Operating System

It detects the operating system (Windows, macOS, Linux, iOS, Android) and often the version. This helps when issues are OS-specific, such as rendering differences between Windows and macOS.

Device Type

The tool classifies the device as Desktop, Tablet, or Mobile. This is useful for responsive design verification and for support when users report mobile-specific issues.

User Agent String

The raw user agent string is often displayed for advanced users and developers who need the exact value. This string is what servers and scripts use for detection; having it visible helps with debugging.

Language and Locale

Accepted languages and locale preferences are shown. This supports internationalization efforts and helps when debugging language or regional content issues.

How to Use

1. Open the What Is My Browser tool in your web browser. No URL or input is required.
2. The tool automatically detects your browser and device. Results appear immediately on the page.
3. Review the displayed information: browser name and version, operating system, device type, user agent, and other details.
4. Copy or share the information if needed. Many tools provide a copy button or a shareable link.
5. Use the information for troubleshooting, support requests, or verification. Visit from different browsers or devices to compare.

Common Use Cases

• Checking what browser and version you are using before contacting support
• Verifying that a website correctly detects your device as mobile or desktop
• Gathering environment information for bug reports or compatibility issues
• Testing browser detection logic during development
• Confirming that a VPN or proxy does not alter your reported browser
• Checking language and locale settings for internationalization
• Comparing detection results across different browsers on the same device
• Providing accurate browser info when a site asks you to upgrade
• Debugging why a site behaves differently on your phone vs computer
• Verifying user agent for analytics or tracking setup

Tips & Best Practices

User agent strings can be spoofed. Some browsers or extensions allow users to change the reported user agent. For critical security or access control, do not rely solely on user agent detection. Use feature detection or server-side checks where possible.

Browser and OS detection is not always perfect. New browser versions or obscure browsers may not be recognized. The tool does its best to parse the user agent; edge cases may show "Unknown" or partial information.

When sharing results with support, include the full user agent string if asked. It contains more detail than the parsed summary and can help with deep troubleshooting. Some tools offer a "copy all" or shareable link for easy transmission.

Visit the tool from the exact browser and device where you are experiencing the issue. Browser profiles, incognito mode, or different devices can report different information. For accurate troubleshooting, use the affected environment.

Limitations & Notes

Detection is based on the user agent and other headers sent by the browser. These can be modified by extensions, privacy tools, or browser settings. Incognito or private mode may change some headers. Results reflect what the server receives, which may not always match the actual browser.

Some browsers intentionally simplify or obscure their user agent for privacy. This may make detection less accurate. The tool uses common parsing rules; unusual or new user agent formats may not parse correctly.

The tool does not detect installed plugins, JavaScript capabilities, or other client-side features. For comprehensive environment information, combine with other diagnostic tools.
