See exactly what your browser reveals about you. Analyze canvas rendering, WebGL info, audio processing, navigator properties, and more.
Renders shapes and text on a hidden canvas, then hashes the pixel data. Different hardware produces unique renderings.
Extracts GPU renderer, vendor, and extensions from WebGL. Graphics hardware details are highly identifying.
Processes an oscillator signal through AudioContext. Subtle hardware differences produce unique signatures.
Collects user agent, platform, languages, hardware concurrency, device memory, and more.
Captures resolution, color depth, pixel ratio. Combined with other signals, display data increases uniqueness.
Estimates how unique your fingerprint is based on all collected data points and their rarity.
Click Analyze Fingerprint. The tool runs Canvas, WebGL, AudioContext, and Navigator API tests in your browser.
Browse categorized results showing exactly what your browser reveals: rendering signatures, hardware info, and system preferences.
Check your estimated uniqueness score. A high score means trackers can easily identify you across websites.
Browser fingerprinting has become one of the most sophisticated tracking techniques on the web. Unlike cookies, which users can delete or block, fingerprints are derived from your hardware and software configuration — making them persistent and difficult to avoid.
Websites collect dozens of data points: your GPU model, canvas rendering output, audio processing characteristics, screen dimensions, installed fonts, and browser settings. Together, these create a unique identifier that can track you across websites without storing anything on your device.
For web scrapers and data collectors, fingerprinting poses a particular challenge. Anti-bot systems use fingerprinting to detect automated browsers. A headless Chrome instance with default settings has a highly distinctive fingerprint that's easy to flag.
Understanding your fingerprint is the first step to controlling it. Use this tool to identify what you expose, then combine anti-fingerprinting techniques with SpyderProxy's rotating proxies for comprehensive anonymity.
Browser fingerprinting identifies users by collecting unique characteristics of their browser and device — screen resolution, GPU renderer, canvas rendering, and more. Unlike cookies, fingerprints can’t be easily deleted because they’re derived from your hardware and software.
The tool draws text, shapes, and gradients onto a hidden Canvas element. Due to differences in GPU, drivers, and font rendering, the pixel data varies between machines. This data is hashed to produce a unique fingerprint string.
Created by generating a tone using the Web Audio API and processing it through audio nodes. Hardware and software differences in audio processing produce measurable variations, creating a unique signature without any audible sound.
Yes. A VPN hides your IP but fingerprinting operates independently of your network. It relies on browser and hardware characteristics that remain the same regardless of your IP address.
Use Tor or Brave with fingerprinting protection. Extensions can randomize canvas and WebGL data. For scraping, use headless browsers with stealth plugins to present a generic fingerprint.
It estimates how distinguishable your browser is. A higher score means your browser stands out more, making it easier for trackers to identify you without cookies.
No. All tests run entirely in your browser using client-side JavaScript. No fingerprint data or hashes are sent to our servers.
Combine IP masking with anti-fingerprinting. SpyderProxy's rotating proxies give you a fresh identity on every request.
