Pixelscan

Pixelscan is a diagnostic tool that checks how visible and trackable your proxy or VPN connection is to websites. You visit the site, click a button, and within seconds it runs a battery of tests across your browser fingerprint, IP information, VPN configuration, DNS routing, and bot detection patterns. It then shows you the results: whether your VPN is leaking your real IP, whether your DNS queries are leaking, how unique your browser fingerprint is, and whether you appear to be a bot. The entire service is free, requires no registration, no account creation, and no data is stored or logged. Once you leave the page, your test results are gone.

The motivation behind Pixelscan is straightforward. If you're running a proxy or VPN specifically to hide your identity or location from websites, you want to know whether it's actually working. Websites have many ways to detect a proxy besides looking at your IP address alone. They can check whether your browser's reported language and timezone match your IP's geolocation. They can analyze your browser fingerprint, looking for signs of antidetect browsers or automation. They can run WebRTC leak tests to see if your real IP leaks through your browser's peer connection. They can check for DNS leaks where your actual DNS resolver betrays your real location. Pixelscan bundles all of these checks into one tool so you can validate whether your proxy setup is actually masking your identity as intended.

The fingerprint check analyzes your browser's attributes: the user agent, screen resolution, installed fonts, WebGL capabilities, canvas fingerprint, and dozens of other properties that web pages collect to build a unique profile of your browser. Pixelscan scores how unique your fingerprint is on a scale, helping you understand how identifiable you are by fingerprinting alone. If you're using an antidetect browser like Multilogin or Linken Sphere, this tells you whether the browser is successfully randomizing these attributes or whether patterns are still leaking through.

The VPN check tests whether your VPN is actually masking your IP. It shows you the IP address the website sees when you're connected to your VPN, the geolocation of that IP, the ISP and company associated with it, and flags any leak. If your VPN is misconfigured or your VPN provider is leaking your real IP, this test catches it immediately. Many users discover through this check that their VPN is leaking WebRTC connections or that their DNS resolver is betraying their real location even though their IP appears correct.

The DNS leak test is critical if you're serious about privacy or evading detection. Your DNS resolver is the service that translates domain names into IP addresses. If your DNS queries are going to your ISP or an unencrypted resolver, a website or network observer can see which sites you're visiting even if your IP and browser are masked. Pixelscan checks whether your DNS is leaking by querying a test domain and seeing which resolver responds. If you're using a VPN, your DNS should route through the VPN provider's DNS, not your ISP's. If it's not, Pixelscan flags it.

The IP blacklist check scans whether your current IP is flagged as a proxy, VPN, datacenter, or botnet IP in various public and private blocklists. Many websites check against these lists to reject obvious proxies. If your IP is flagged, some websites will block you even if your other indicators look clean. Pixelscan shows you which lists have flagged your IP, helping you understand what level of detection you're facing.

The WebRTC leak test exploits a browser vulnerability that can leak your real IP through WebRTC connections used for video calls and peer-to-peer communication. Even if your VPN masks your IP in all other traffic, a WebRTC connection can peer directly to the internet and reveal your actual IP. This is a known leak vector that many proxy and VPN users don't realize exists. Pixelscan tests for it.

The bot detection check analyzes your browser for signs of automation. Modern websites use bot detection libraries like Cloudflare's, PerimeterX, and others to identify automated traffic and block bots. If you're using your proxy setup for legitimate browsing, you'll want to know whether your setup looks like a bot to these detection systems. Pixelscan checks against these patterns and flags if your browser appears automated.

You can also check your location consistency across IP, timezone, and language. A website sees your IP's reported geolocation, your browser's timezone setting, and your browser's language preferences. If these three don't match (you're on a German IP but your browser language is Japanese and your timezone is US Eastern), it's a red flag that something is masked or misconfigured. Pixelscan highlights these inconsistencies.

The platform's interface is minimal and direct. You visit pixelscan.net, click "Start Scan" or similar, wait about five seconds, and your results appear. The scan works across residential proxies, datacenter connections, mobile proxies, and major VPN services including Nordvpn, ExpressVPN, and others. Pixelscan also includes a cookie converter utility that transforms cookie data into JSON format, which can be useful if you're debugging cookie handling with your proxy setup.

Pixelscan reports high accuracy on its claims. The site states a 99.95 percent accuracy rate and reports over five million scans performed. These numbers are not independently verified, but the tool's checks are objective and technical in nature, so high accuracy is plausible. A leak test either detects a leak or it doesn't. A bot detection check either flags automation patterns or it doesn't.

The data retention policy is a core selling point. Pixelscan explicitly states that test results are not stored, not linked to any identity, and not logged. Your test results disappear when you leave the page. This is important for privacy-conscious users who don't want their proxy configuration testing itself logged somewhere. The transparency on this point is valuable.

One limitation is that Pixelscan is purely a diagnostic tool. It tells you what's leaking and what isn't, but it doesn't fix problems. If you discover a DNS leak, Pixelscan doesn't help you configure your VPN to use encrypted DNS. If your browser fingerprint looks too unique, Pixelscan doesn't help you randomize it (though an antidetect browser would). If your IP is flagged in blocklists, you'll need to switch to a different IP. Pixelscan is the check, not the remedy.

For anyone running proxies or VPNs who needs to know whether their setup is actually working, Pixelscan is a simple and reliable tool. The free cost, no-registration requirement, and zero data retention make it an obvious first check before trusting your proxy setup for anything important. It won't solve your problems, but it will clearly show you what problems exist.
