Check Your Device Information Instantly
Welcome to DeviceScope, a fast and privacy-friendly device information checker. Whether you're a web developer, a QA tester, or just trying to find your device specifications, our online device checker gives you immediate access to your system diagnostics. There's no software to install, no account required, and most importantly, no invasive tracking.
When you load this page, your browser securely shares basic diagnostic data through standard web APIs. DeviceScope processes this data entirely in your browser, allowing you to instantly check your deviceinformation including your screen resolution, browser details, operating system, and network connection.
What Can DeviceScope Check?
Our diagnostic platform categorizes your device information into four main areas. Each metric has a dedicated tool page that explains what the metric is, why it matters, and how it impacts your experience.
Screen and Display Information
Understanding your display capabilities is critical for web design and media consumption. DeviceScope acts as a comprehensive display resolution checker and screen size checker. We detect:
- Screen Resolution: The total physical pixels your monitor can display.
- Viewport: The actual available space for rendering web pages inside your browser window.
- Device Pixel Ratio (DPR): To determine if you are using a Retina or high-DPI screen.
- Orientation: Whether you are in portrait or landscape mode.
- Color Depth: How many colors your screen can render.
- Refresh Rate: An estimation of your monitor's Hz output for smooth scrolling and gaming.
Browser and System Information
When troubleshooting web applications, a browser information checker is essential. Your system configuration dictates what web technologies are supported on your machine. We check:
- Browser and Version: Which web engine is currently parsing this page.
- Operating System: Are you on Windows, macOS, Linux, iOS, or Android?
- User Agent: The exact string your browser sends to web servers to identify itself.
- Language and Timezone: Your system's localization settings.
- Platform: Whether you are on a mobile phone, tablet, or desktop machine.
Why Check Your Device Information?
Device diagnostics aren't just for curiosity; they are vital for building and maintaining digital products.
- Developers and Web Designers: Need to verify responsive breakpoints against actual viewport sizes and ensure their applications work perfectly on specific browser versions and operating systems.
- QA Testers: Use our device test tools to record exact environment variables when reproducing bugs.
- IT and Customer Support: Can easily direct users to DeviceScope to quickly figure out their computer information without asking them to navigate confusing OS settings menus.
- General Users: Can use our system information checker to verify their new monitor's refresh rate, confirm their public IP address, or check if their browser is leaking unexpected tracking data.
Privacy-Friendly Device Diagnostics
DeviceScope is built with privacy at its core. When you use our online device checker, you are interacting with standard Web APIs built into your browser.
We do not use invasive fingerprinting techniques, and we do not store your device profile on our servers. The vast majority of the information you see on your dashboard is calculated locally on your machine and never leaves your browser. Information that requires an external request, such as your public IP address, is processed without logging your identity. For sensitive APIs like your camera and microphone, DeviceScope will always require your explicit permission before attempting to access them.
Frequently Asked Questions
Have questions about your device, browser, or system information? Find answers to some of the most common questions people ask about identifying and understanding their devices.
What is my device?
DeviceScope can identify available browser and device information such as your operating system, browser, browser version, platform, screen resolution, viewport, device pixel ratio, and touch capability. Modern browsers intentionally restrict some device information for privacy and security, so a website cannot always identify the exact physical device model.
How do I find out what my device is?
DeviceScope provides browser-accessible information about your device and operating environment without requiring any software installation. You can instantly see what information is detectable from your browser, while understanding what remains private.
Which model is my device?
Exact device model detection is not always available through standard browser APIs. While browser information provides useful clues that we display, we cannot always identify the exact physical model. Mobile operating systems and browsers increasingly restrict precise hardware identification to protect your privacy.
What is my device name?
A browser may not expose the custom device name you configured in your system settings. There is a difference between your custom device name, device model, operating system, browser, and user agent. If the exact custom name is unavailable to the browser, it cannot be displayed.
Is my device Android?
DeviceScope can detect the operating system and platform information exposed by your browser. We check reliable browser APIs beyond just the user agent to help you determine if your device is running Android.
How do I confirm my device name?
DeviceScope can show available browser and operating-system information. However, a custom device name configured by the user is typically not exposed to websites for privacy reasons.
How do I see the full name of my device?
The full device name shown inside your operating system settings is different from the information detectable by a browser. DeviceScope provides all available browser and device data, but cannot guarantee access to your private, full system device name.
How do I check my device without logging in?
DeviceScope is designed to work directly in your browser without requiring an account. We process diagnostic data locally in your browser to check your device without logging in, and we do not store your device profile on our servers.
What is my device IP address?
An IP address identifies the network connection visible to a service. You can check your IP address to see your public IP. Note that websites cannot reliably expose your private or local IP address on your internal network.
What is my device IP?
Your public IP is the address visible to the websites you visit. You can easily check your IP address using our dedicated tool.
What is my device ID?
Websites generally cannot access a permanent hardware or device identifier because of browser privacy restrictions. DeviceScope provides browser-exposed identifiers where appropriate, but it cannot retrieve a permanent hardware ID.
