Browser & Device Fingerprint Information

Every browser exposes a rich set of information to every website it visits — without requiring any special permissions or plugins. This tool displays all the data your browser makes available through standard JavaScript APIs.

Data Points Collected

• User-Agent — Browser name, version, operating system and engine reported by the browser.
• Platform — The operating system platform string (e.g. "Win32", "MacIntel", "Linux x86_64").
• Language — Your preferred browser language and the full list of accepted languages.
• Screen Resolution & Color Depth — Physical display dimensions and color bit depth.
• Device Pixel Ratio — Retina/HiDPI display indicator. A value of 2 indicates a Retina display.
• CPU Cores — The number of logical CPU cores reported by the browser (used for fingerprinting).
• RAM — Approximate device memory reported in GB (rounded to nearest bucket: 0.25, 0.5, 1, 2, 4, 8 GB).
• Timezone — Your system timezone as reported by the Intl API.
• WebGL Support — Whether hardware-accelerated 3D graphics are available.
• Touch Support — Whether the device has a touch screen.
• Cookie & localStorage — Whether these storage mechanisms are enabled.

Browser Fingerprinting

The combination of these data points creates a highly unique "fingerprint" that can identify your browser across different websites and sessions without using cookies. Studies show that browser fingerprints are unique for over 90% of users. Privacy-focused browsers like Firefox with resistFingerprinting, or Brave, attempt to normalize these values to reduce uniqueness.
