Browser Information Checker

Browser Information Checker

Browser Information Checker lets you view detailed information about the current browser and runtime environment, including browser name and version, operating system, device type, User Agent, screen resolution, language, timezone, CPU cores, network environment, GPU, WebGL, and browser storage capabilities.

What Does the Browser Information Checker Detect?

When a browser visits a webpage, it provides various runtime environment details. Browser information detection helps you quickly understand the current browser and device environment for website development, frontend debugging, browser compatibility checks, and Web application testing.

Browser Information

• Browser: Detects the name of the current browser.
• Browser Version: Shows the current browser version.
• Language: Shows the browser's preferred language.
• Language List: Shows the browser's configured language priority.
• Online Status: Detects whether the browser is currently online.
• Cookie: Detects whether the browser supports cookies.
• Do Not Track: Shows whether the browser has enabled Do Not Track requests.
• User Agent: Shows the User-Agent string sent by the browser.

Screen and Device Information

The tool can read screen and device information accessible to the browser to help understand the current webpage runtime environment.

Screen Information

• Screen Resolution: Shows the current screen width and height.
• Available Size: Shows the screen dimensions available to the browser from the operating system.
• Color Depth: Shows the screen color bit depth.
• Device Pixel Ratio: Shows the ratio between CSS pixels and physical pixels.
• Screen Orientation: Shows whether the screen is currently in landscape or portrait orientation.

System Information

• System Platform: Shows the operating system platform reported by the browser.
• CPU Cores: Shows the number of logical processors available to the browser.
• Device Memory: Shows device memory when supported by the browser API.
• Touch Points: Shows the maximum number of supported touch points.
• Mobile Device: Indicates whether the current environment is a mobile device.
• Timezone: Shows the IANA timezone used by the browser.
• Locale: Shows the browser's current locale setting.
• UTC Offset: Shows the current timezone offset from UTC.

Network and Graphics Information

Network Information

When supported by the browser's network APIs, the tool can show the current connection type, estimated download speed, network latency, and data-saving mode. Some fields may be empty because of browser, operating system, or network limitations.

GPU Information

GPU information helps identify the graphics device and WebGL rendering environment currently used by the browser. It can assist with troubleshooting compatibility issues involving animations, Canvas, WebGL, and graphics rendering.

• GPU Vendor: Shows graphics hardware vendor information obtained by the browser.
• GPU Renderer: Shows the current WebGL graphics renderer information.
• WebGL Version: Shows the WebGL version supported by the browser.

Browser Storage Detection

The tool can also detect common browser-side storage capabilities to help developers determine whether the current environment supports local data storage commonly used by Web applications.

Supported Storage Types

• Local Storage: Detects support for persistent local storage.
• Session Storage: Detects support for session-based storage.
• IndexedDB: Detects support for IndexedDB database storage.

Browser Information Checker Use Cases

• Website and Web application frontend development
• Browser compatibility testing
• User Agent and browser version lookup
• Screen resolution and device pixel ratio detection
• Mobile and desktop environment detection
• WebGL and GPU rendering troubleshooting
• Browser storage capability detection
• Website troubleshooting and frontend runtime environment analysis

How to Use the Browser Information Checker?

1. Open the Browser Information Checker page.
2. The browser automatically reads information available from the current webpage environment.
3. View browser, system, screen, network, GPU, and storage detection results.
4. Use the results for web development, compatibility testing, or troubleshooting.

Frequently Asked Questions

Is browser information detection safe?

The tool mainly reads runtime environment information publicly provided by the browser and does not require a browser extension. Some advanced device information is restricted by browser permissions and privacy policies, so available fields may differ between browsers.

Why are some detection results empty?

Some information depends on browser Web APIs, such as device memory, network speed, and connection type. If the browser does not support the relevant API or restricts it for privacy reasons, the corresponding field may not be available.

What is User Agent?

User Agent is a string used by the browser to identify the client software and platform. Websites can use User Agent information to determine basic browser and operating system details.

Can the real IP address be detected?

Browser information detection focuses on the client runtime environment and is not the same as an IP address lookup tool. To view a public IP address and related network information, use a dedicated IP address lookup tool.

Privacy Notice

The information shown by browser detection mainly comes from client-side APIs provided by the current browser. Because browser and operating system privacy policies differ, results may vary and some sensitive or restricted information may not be provided.
