What is StealthHound?

StealthHound is a browser extension that exposes and blocks hidden browser fingerprinting and silent tracking in real time. It works even when websites don’t use cookies or require logins. The extension runs fully locally in your browser with zero data collection, delivering instant risk signals (Low/Medium/High), live alerts, and automatic blocking of invasive techniques like canvas fingerprinting, API abuse, and hardware probing. StealthHound makes invisible tracking visible and gives you full control over who’s profiling your device.

Who it’s for

• Privacy-conscious users who want to see exactly which websites are tracking them and how, without relying on vague browser settings.
• Developers and tech professionals who need granular insight into tracking scripts and fingerprinting attempts to audit site behavior.
• Anyone tired of being profiled who wants automatic, real-time protection against silent data collection without sacrificing browser performance.

Key features

Real-Time Risk Score

StealthHound assigns a live risk score (Low/Medium/High) to every website based on its tracking activity. You instantly know whether a site is safe or actively trying to fingerprint your device.

Live Tracking Alerts

You receive immediate notifications when a website attempts canvas fingerprinting, hardware probing, or API tracking. No more wondering if you’re being watched — StealthHound tells you the moment it happens.

Automatic Tracker Blocking

Invasive tracking techniques are stopped in the background without any manual intervention. Canvas fingerprinting, API abuse, and hardware probing are blocked before they can build a profile of your device.

Tracking History

A detailed log shows which websites attempted tracking and when. You can review the full timeline of tracking attempts to understand patterns and identify repeat offenders.

What stands out

StealthHound focuses on visibility and protection, so you always know what’s happening.

VPNs hide your IP but don’t stop fingerprinting. Ad blockers remove ads but often miss hidden tracking. Browsers block silently without showing what happened. StealthHound combines real-time detection, automatic blocking, and full transparency — all running locally with no data collection and no browser slowdown. It’s the only tool that shows you exactly who’s tracking you and how, then shuts it down before profiling starts.
