How to use the Device Info Checker
Open the page: the summary at the top shows the device type, OS, browser, CPU, memory and screen right away.
Scroll through the cards for details on the system, graphics, display, input, network, battery and sensors.
Check the Graphics card: if it says software rendering, turn on hardware acceleration in your browser settings.
Click Copy report to paste everything into an email or support ticket, or download it as a TXT or JSON file.
Click Check again after plugging in a charger, rotating the screen or changing networks to refresh the values.
Where each value comes from
Web pages cannot read your hardware directly. Every value on this page comes from a standard browser API, and some browsers limit or round them to protect your privacy.
Value
Browser API
Availability and accuracy
Operating system, browser
User agent string, User-Agent Client Hints
Exact versions in Chrome and Edge; macOS frozen at 10.15.7 in Safari and Firefox
CPU cores
navigator.hardwareConcurrency
Logical processors (threads); Safari may report fewer
Memory
navigator.deviceMemory
Chromium only, rounded and capped at 8 GB
Graphics card
WebGL WEBGL_debug_renderer_info
Most browsers; Safari and Firefox may show a generic name
Screen, pixel ratio
screen, devicePixelRatio
All browsers; values change with zoom and display scaling
Refresh rate
Measured with requestAnimationFrame
Median frame interval over 1 second; reads lower in power-saving mode
Network
Network Information API
Chromium only; speed is a rounded estimate, not a speed test
Battery
Battery Status API
Chromium on desktop and Android; not in Firefox or Safari
Understanding resolution and pixel ratio
Browsers measure screens in CSS pixels. On high-density displays one CSS pixel covers several physical pixels: the device pixel ratio (DPR). Physical resolution ≈ CSS resolution × DPR. A phone reporting 390 × 844 at 3x really has about 1170 × 2532 pixels, and a laptop at 1536 × 864 with 1.25x scaling is a 1920 × 1080 panel. Browser zoom also changes the DPR, so set zoom to 100% for accurate numbers.
Sharing your device info with support
Use Copy report or Download TXT to give a support team everything at once instead of answering questions one by one.
The report contains no names, serial numbers, IP or location; check it before sharing if you prefer, it is plain text.
If the graphics card shows software rendering, turn on hardware acceleration in the browser settings and click Check again.
Battery and network values update live; click Check again after changing networks or plugging in a charger.
Frequently asked questions
Why does the memory show 8 GB when my computer has more?
Browsers report device memory through navigator.deviceMemory, which is deliberately rounded and capped for privacy. Chrome and Edge report 0.25, 0.5, 1, 2, 4 or 8 GB, so any device with 8 GB or more shows 8 GB. Firefox and Safari do not report memory at all.
Is the CPU core count accurate?
The page shows navigator.hardwareConcurrency, the number of logical processors the browser may use. On CPUs with Hyper-Threading or SMT this is usually twice the number of physical cores. Safari may report a lower number, and some privacy settings cap or randomise it.
Why does my Mac show macOS 10.15.7?
Safari and Firefox freeze the macOS version in the user agent at 10.15.7 to reduce fingerprinting, so the real version cannot be read. Chrome and Edge reveal the real version through User-Agent Client Hints, which this page reads automatically.
How can I tell Windows 11 from Windows 10?
Both send "Windows NT 10.0" in the user agent. Chrome and Edge also provide a platform version through User-Agent Client Hints: 13 or higher means Windows 11, 1 to 12 means Windows 10. Firefox cannot distinguish them, so the page shows Windows 10 or 11.
Why is my graphics card shown as SwiftShader or software?
The browser is drawing graphics on the CPU instead of the GPU. This happens when hardware acceleration is switched off in the browser settings, when the graphics driver is blocklisted, or inside a virtual machine or remote desktop. Turning hardware acceleration on and updating the driver usually fixes it.
Does this page collect my device information?
No. Everything is read and displayed locally in your browser and nothing is sent to a server. The report only leaves the page when you copy or download it yourself.
