Inspect a Website
See what information a website exposes publicly (Headers, DNS, Security) without revealing your own data.
❓ Why can websites see this?
It's not magic, it's how the internet works. When you visit a website, your browser sends a request to the server. Included in that request are "headers"—bits of information like your IP address (so the server knows where to send the page back) and your User-Agent (so the server sends the desktop version instead of mobile).
Other details, like your screen size and time zone, are detected using JavaScript to make the website look and function correctly on your specific device. While this data is necessary for functionality, it can also be combined to create a "fingerprint" of your device.
📊 IP vs Cookies vs Fingerprinting
| Method | How it works | Can you block it? |
|---|---|---|
| IP Address | Network address assigned by your ISP. Required for connection. | Yes, use a VPN. |
| Cookies | Small text files saved on your device to remember login/prefs. | Yes, clear cookies or use Incognito. |
| Fingerprinting | Combining screen, GPU, font, and version data to identify you. | Hard. Use privacy browsers (Brave/Tor). |
