About DeviceInfo.io

DeviceInfo.io is a free suite of online tools designed to help you quickly discover technical information about your device, network, and browser. Whether you need to check your IP address, screen resolution, browser version, or graphics card, our tools provide instant, accurate results right in your browser.

Our Mission

We believe that understanding your own device and network information should be simple, fast, and free. DeviceInfo.io was created to provide a reliable, privacy-respecting way for anyone to access essential technical details about their system without downloading software, creating accounts, or sharing personal data.

Our goal is to be the most trusted and comprehensive device information resource on the web, serving everyday users, IT professionals, web developers, and system administrators alike.

What We Offer

DeviceInfo.io provides a growing collection of free diagnostic and information tools:

  • IP Address Lookup: Instantly view your public IP address, geographic location, and Internet Service Provider (ISP) details. Useful for verifying VPN connections, troubleshooting network issues, and configuring firewalls.
  • Screen Size Checker: Detect your screen resolution, browser viewport dimensions, pixel ratio (Retina/HiDPI), and display type. Essential for web designers, developers, and anyone choosing wallpapers or optimizing their display settings.
  • Browser Detector: Identify your web browser name, version, rendering engine, and supported capabilities. Helpful for troubleshooting website compatibility issues and ensuring your browser is up to date.
  • GPU Detector: Find out which graphics card your browser is using, including vendor, model, and WebGL capabilities. Great for gamers checking hardware requirements and developers testing WebGL features.
  • Device Specs: Get a comprehensive overview of your hardware including CPU cores, RAM, display, GPU, browser, and network information all on one page. Perfect for copying and sharing your system details for tech support.

Privacy First

Your privacy is our top priority. Here's how we protect it:

  • No data storage: We do not store your IP address, device information, or any personal data on our servers. All detection happens locally in your browser.
  • No accounts required: You never need to sign up, log in, or provide an email address to use any of our tools.
  • No software downloads: Everything works directly in your web browser using standard web APIs.
  • Transparent practices: We clearly disclose our use of third-party services (Google Analytics for site improvement, Google AdSense for advertising) in our Privacy Policy.
  • Cookie consent: We ask for your consent before enabling analytics or advertising cookies, and you can reject them at any time.

How It Works

Our tools use standard web browser APIs to detect your device information. When you visit a page, your browser provides access to certain system details through JavaScript APIs like the Navigator API, Screen API, WebGL API, and Network Information API. We read this information and display it to you in a clear, organized format.

For IP address detection, we make a single request to a geolocation API to retrieve your public IP and approximate location. This is the only network request involved in our detection process, and the data is displayed directly to you without being stored.

Who Uses DeviceInfo.io?

  • Everyday users: Checking their IP address, verifying VPN connections, or finding their screen resolution.
  • Web developers: Testing viewport sizes, browser capabilities, and WebGL support across devices.
  • IT professionals: Quickly gathering system information for troubleshooting and support tickets.
  • Gamers: Checking GPU details and system specs against game requirements.
  • Tech support: Asking users to share their device specs for remote troubleshooting.

Accuracy and Limitations

While we strive for accuracy, browser-based detection has inherent limitations. Security and privacy protections in modern browsers restrict access to some hardware details. IP geolocation is approximate (typically city-level) and may be affected by VPN usage, proxy servers, or mobile networks. For complete hardware specifications, we recommend using your operating system's built-in system information tools alongside our browser-based detection.
