What does this tool show?

This tool displays detailed information about your current browser, operating system, screen, network, and connection – basically everything websites can detect about you when you visit them. Useful for: debugging website issues (knowing your exact browser version), checking your public IP for security/troubleshooting, understanding what data sites collect about you (privacy awareness), verifying your VPN is active (different IP than usual), confirming screen resolution for design work, or checking timezone after travel. All information comes from your own browser via standard APIs – no signup, no tracking, no data stored on our server. Your IP is fetched from a free public API (ipify.org).

How to use this tool

1. Open the page — Tool auto-detects everything when page loads. No clicks or inputs needed.
2. Browser info — Browser name + version, OS, mobile/desktop detection, language preference, timezone.
3. Screen info — Resolution (full screen), viewport (visible area), color depth (8/16/24/32-bit), pixel ratio (1x for standard, 2x for retina).
4. Connection info — Public IP address (your network’s external address), online status, cookies enabled, CPU cores available.
5. User Agent — Raw user agent string – what websites actually see. Used by support teams to diagnose browser-specific issues.

Why this information matters

For users (privacy awareness):

• Every website you visit can see all this info – know what you’re sharing
• VPN verification: if IP doesn’t match your country/city, VPN is working
• Mobile vs desktop detection – explains why some sites show different layouts
• Language preference – sets default language on sites that support multiple

For developers (debugging):

• Reproduce user-reported issues – same browser/OS/screen helps
• Test mobile-specific issues by detecting mobile flag
• Time-sensitive bugs – timezone affects date/time calculations
• Performance issues – CPU cores and viewport size matter

For support (troubleshooting):

• ‘It works on my machine’ – User Agent shows differences
• Color rendering issues – color depth matters
• Touch vs click – mobile detection

Examples

• Office worker in Mumbai: Browser: Chrome 120, OS: Windows 11, IP: 49.x.x.x (Mumbai), Timezone: Asia/Kolkata, Screen: 1920×1080
• iPhone user: Browser: Safari 17, OS: iOS, Mobile: Yes, IP: 100.x.x.x (Reliance Jio), Screen: 390×844, Pixel ratio: 3x
• Designer’s setup: Browser: Firefox, OS: macOS, Screen: 5120×2880 (5K), Pixel ratio: 2x
• VPN active: IP suddenly shows different country/city – VPN working properly
• Mobile browser test: Open in Chrome desktop with mobile device emulation – viewport changes but user agent reveals desktop

Tips & best practices

• Your public IP is unique to your network connection – changes when you switch WiFi/mobile/VPN
• User Agent strings are increasingly inaccurate – many browsers spoof user agents for privacy
• Pixel ratio above 1 = retina/high-DPI display – images should be 2x or 3x resolution for sharpness
• Color depth almost always 24 or 32 in 2026 – older systems had 16-bit
• Hardware concurrency = CPU cores available to browser – useful for Web Worker count
• Cookies disabled = many sites won’t work – check this setting if seeing ‘enable cookies’ errors
• Timezone detected from browser, not IP – travelers see their phone’s timezone

Limitations & notes

User Agent strings are increasingly unreliable – many browsers (especially newer Chromium-based) spoof or simplify them for privacy. IP location can be inaccurate by hundreds of km – especially for mobile networks where IPs route through different cities. VPN/proxy users show their VPN exit IP, not their real location. CPU cores reported is what browser can use – may be lower than physical cores due to OS limits.

Frequently Asked Questions

Is the IP address my real one?

It’s your PUBLIC IP – what websites see. Your local network IP (192.168.x.x or 10.x.x.x) is different and not visible to websites. If you’re using VPN/proxy, you see the VPN’s exit IP, not your real one – this is the privacy feature working.

Why is my browser version different from what I expected?

Sometimes browsers report wrong/older versions for compatibility. Chrome on iOS uses Safari engine but says ‘CriOS’ (Chrome iOS). Some browsers freeze user agent at older versions. Your actual browser might be newer than reported.

What is ‘User Agent’?

The complete identifier string your browser sends to every website. Format: Mozilla/5.0 (OS) Browser/Version etc. Used by sites to detect your browser and serve appropriate content. Increasingly being deprecated in favor of UA hints API.

Why is my screen resolution different from viewport?

Screen resolution = total monitor pixels. Viewport = visible browser area (smaller after subtracting taskbar, browser chrome, etc.). On 1920×1080 monitor, viewport may be 1536×720 with various UI elements taking space.

What does pixel ratio mean?

How many physical pixels per CSS pixel. 1x = standard. 2x = retina/HiDPI displays where each CSS pixel is 2×2 physical pixels. 3x = newer iPhones. Higher pixel ratio = sharper images but require 2x or 3x assets to look crisp.

How do I find my MAC address?

Not via web browsers – browsers don’t expose MAC addresses for security. To find your MAC address: Settings → About → Status (Windows). System Settings → Wi-Fi → details (Mac). Settings → About phone (Android/iOS). Browsers ONLY see IP, not MAC.

Is this info stored anywhere?

No – displayed in your browser only. IP comes from api.ipify.org (free service that doesn’t store IPs). We don’t log anything from this page. Everything you see came from your own browser’s APIs.
