Browser Fingerprint Test
Analyze the Canvas, WebGL, Audio, font and hardware signals that websites use to identify and track your browser. Detect fingerprint spoofing, open ports, and automation markers — entirely client-side.
A higher score means your browser looks like a normal, un-tampered device. Automation, spoofing or dev-tools lower it.

What is a browser fingerprint?
A browser fingerprint is a collection of attributes — user-agent, screen resolution, installed fonts, Canvas and WebGL rendering, AudioContext output, timezone, language, and hardware specs — that together can uniquely identify your device without cookies. Websites and anti-fraud platforms combine these signals to recognize returning visitors and flag automation or spoofed environments.
Why test your browser fingerprint?
Testing reveals exactly what trackers see and how identifiable you are. A consistent, natural fingerprint avoids CAPTCHAs and blocks. An inconsistent one — mismatched values, tampered APIs, automation markers — is a red flag. For multi-account workflows, pair a clean device profile with a residential proxy so your IP matches your fingerprint.
What about antidetect browsers?
Antidetect browsers like Multilogin, GoLogin, AdsPower, Dolphin Anty, and Incogniton create isolated profiles with spoofed fingerprints. They are useful for multi-account management, but they can leave detectable traces: Canvas noise injection, WebGL parameter mismatches, inconsistent Navigator properties, timezone discrepancies, and unusual port activity. A thorough fingerprint test helps verify whether your setup passes real-world detection.
Why does port scanning matter?
Websites can probe your local ports using WebSocket or fetch timing to detect software running on your machine — SSH clients, remote desktop tools like TeamViewer or AnyDesk, SOCKS proxies, and development servers. Open ports reveal your environment and can be used alongside fingerprint data to build a more complete device profile or flag suspicious setups.
What signals are checked?
We analyze Canvas rendering for noise injection, WebGL for renderer and vendor spoofing, AudioContext for processing anomalies, font enumeration, Navigator API integrity, timezone consistency with your IP, open local ports, and automation markers from Selenium, Puppeteer, or Playwright. Each signal is scored independently — a single mismatch may not matter, but multiple failures strongly indicate a non-standard browser environment.
Frequently asked questions
What is browser fingerprinting?
Browser fingerprinting is a technique that collects unique characteristics of your browser and device — such as screen resolution, installed fonts, WebGL renderer, and canvas rendering — to create a distinctive identifier without using cookies.
How does a fingerprint scan help me?
A fingerprint scan reveals what information websites can collect about your browser and device. Understanding your digital fingerprint helps you identify privacy risks and take steps to reduce tracking.
What is a canvas fingerprint?
Canvas fingerprinting uses the HTML5 Canvas element to draw invisible graphics. Because different devices render graphics slightly differently due to hardware, drivers, and OS, the resulting image produces a unique hash that can identify your device.
What is WebGL fingerprinting?
WebGL fingerprinting collects information about your graphics hardware and driver through the WebGL API, including the GPU vendor and renderer. This data is highly unique and difficult to spoof.
Can I prevent browser fingerprinting?
Completely preventing fingerprinting is difficult, but you can reduce its effectiveness by using privacy-focused browsers, anti-detect browsers, or browser extensions that randomize fingerprint data points.
What does the Fingerprint Score mean?
The Fingerprint Score assesses how natural and consistent your browser fingerprint appears. A higher score indicates your browser looks like a typical user device, while a lower score may indicate spoofing or unusual configurations.
