What is BrowserScan?
BrowserScan (browserscan.net) is the most comprehensive free browser fingerprinting and privacy testing tool available in 2025. It's a web-based diagnostic platform that reveals exactly what information your browser and network expose to websites when you browse the internet.
Unlike basic IP checkers, BrowserScan performs a holistic browser fingerprint analysis, examining over 50 distinct data points including IP address detection, WebRTC leak testing, DNS leak detection, canvas fingerprinting, WebGL fingerprinting, audio fingerprinting, browser configuration, hardware specifications, and network vulnerabilities. This makes it an essential tool for anyone concerned about online privacy, multi-account management, or antidetect browser configuration.
Why BrowserScan Matters in 2025
As websites become more sophisticated in tracking users, understanding your browser fingerprint is critical for:
- Multi-account management without bans
- Testing antidetect browser configurations
- Verifying VPN/proxy effectiveness
- E-commerce & affiliate marketing
- Social media account security
- Web scraping operations
- Online privacy protection
What sets BrowserScan apart is its fingerprint authenticity score - a unique metric that instantly tells you how trackable your browser is compared to millions of other users. A score above 90% indicates your fingerprint appears natural and authentic, while scores below 90% mean you're leaking information that can be used to track you across websites or identify multiple accounts.

Browser Fingerprint Testing Explained
What is Browser Fingerprinting?
Browser fingerprinting is a tracking technique that collects information about your browser configuration and device to create a unique identifier - your "fingerprint." Even without cookies, websites can recognize you across sessions using this fingerprint.
BrowserScan reveals your complete fingerprint by analyzing:
- Canvas Fingerprinting: How your GPU renders graphics
- WebGL Fingerprinting: 3D graphics rendering signature
- Audio Fingerprinting: Audio stack and processing characteristics
- Font Detection: Installed system fonts list
- Hardware Specs: CPU cores, GPU, memory, screen resolution
BrowserScan Fingerprint Data Points
WebRTC & DNS Leak Detection
WebRTC Leak Danger
WebRTC (Web Real-Time Communication) can expose your real IP address even when you're using a VPN or proxy. This happens because WebRTC creates peer-to-peer connections that bypass your proxy settings.
What BrowserScan Checks:
- โข Internal IP addresses exposed
- โข Public IP through STUN servers
- โข IPv6 leaks
- โข mDNS leaks
A WebRTC leak can completely defeat your VPN/proxy protection, making BrowserScan's real-time WebRTC leak test essential for true anonymity.
DNS Leak Protection
DNS leaks occur when your device sends DNS queries to your ISP's DNS server instead of using your VPN/proxy's DNS. This reveals which websites you're visiting and can expose your true location.
BrowserScan DNS Tests:
- โข DNS server location verification
- โข ISP DNS detection
- โข DNS query routing analysis
- โข Third-party DNS exposure
BrowserScan's DNS leak test ensures your queries are being handled securely through your chosen DNS provider, not leaking to your ISP.
Why Leak Detection is Critical
Even with the best VPN or proxy service, WebRTC and DNS leaks can completely expose your:
Real IP Address
Your actual location and ISP
Browsing Activity
Websites you're visiting
Multiple Accounts
Account linking and bans
Privacy Identity
Cross-site tracking
Understanding Fingerprint Authenticity Score
BrowserScan's fingerprint authenticity score is one of its most valuable features. This 0-100% score instantly tells you how unique and trackable your browser fingerprint is compared to millions of other users.
Excellent Score (90-100%)
Natural, authentic fingerprint
Your browser fingerprint appears legitimate and blends in with typical users. Websites are unlikely to flag you for suspicious activity or track you easily across sites.
Good Score (70-89%)
Acceptable with minor issues
Your fingerprint is mostly natural but has some unusual characteristics. May be trackable on advanced platforms. Consider fixing WebRTC/DNS leaks or adjusting browser settings.
Poor Score (Below 70%)
Highly trackable, action needed
Your fingerprint is leaking significant information that can be used to track you across websites or link multiple accounts. Immediate action required: fix WebRTC leaks, configure antidetect browser, or adjust proxy settings.
How to Improve Your Authenticity Score
- Disable WebRTC in browser settings or use WebRTC blocking extensions
- Configure VPN/proxy with proper DNS leak protection
- Use antidetect browsers like GoLogin, AdsPower, or Multilogin
- Match your timezone and language to your proxy location
- Use high-quality residential or mobile proxies like Coronium
