Device Info

What is Device Info?

Device Info shows your screen resolution, browser version, operating system, CPU cores, memory, and language settings. One page, nothing to configure.

The tool reads values straight from your device using the standard Navigator and Screen Web APIs: user agent string, hardware concurrency, device memory, connection type, touch support, cookie status, GPU model, battery level, and storage quota. Nothing is sent to a server. The Copy all button bundles everything into plain text, Download JSON saves a machine-readable file for bug trackers, and Share report builds a private link you can send to tech support.

How to use

1. Open the tool and your device info appears automatically. No input needed.
2. Check your browser, screen, hardware, and network details.
3. Copy all info to clipboard with one click to paste into a bug report, support ticket, or tech forum post.

When to use

• Filing a GitHub issue and need to include exact browser, OS, and screen specs.
• Helping a relative troubleshoot a website that breaks on their device.
• Confirming what user-agent string a site is seeing before you change a setting.

Result

Someone troubleshooting a website copies their device info (Chrome 126, Windows 11, 1920×1080, 16 cores) and pastes it into a GitHub issue.

FAQ

Does this tool send my device data anywhere?

No. Every value comes from JavaScript APIs that already run inside your browser. The page never makes a network call with your info. Open the network tab while you use it to confirm.

Why does Memory show N/A on my phone?

The deviceMemory API is only implemented in Chromium browsers (Chrome, Edge, Opera, Samsung Internet). Safari and Firefox return undefined for privacy reasons, so we display N/A instead of a guess.

The CPU core count looks too low. Is the number accurate?

hardwareConcurrency reports logical cores available to the browser, not physical ones. Browsers also cap the value (typically at 8 or 16) to limit fingerprinting. A 24-thread workstation often shows 16.

What's the difference between Screen Resolution and Pixel Ratio?

Screen resolution is what the OS reports in CSS pixels. Pixel ratio shows how many physical pixels make up one CSS pixel. A Retina MacBook usually reads 1440 by 900 at 2x, meaning 2880 by 1800 physical pixels.

Can a website see all this when I visit?

Yes. Any site you load can read these same values without asking. That's why fingerprinting is a privacy concern. This tool just makes the values visible to you instead of letting them sit in dev tools.
