About BrowserProbe

BrowserProbe is a free suite of online tools that reveals what information your browser exposes to the websites you visit. Our mission is simple: help people understand and control their digital privacy.

Why We Built This

Every time you visit a website, your browser shares dozens of data points — your screen resolution, GPU model, installed fonts, timezone, and much more. Individually, these seem harmless. Combined, they create a unique "fingerprint" that can track you across the internet without cookies.

Most people have no idea how much data their browser reveals. BrowserProbe makes this visible.

Our Principles

• 100% Client-Side — All detection runs in your browser. We don't send your data to any server (except the IP tool, which only reads request headers).
• No Tracking — We don't use analytics, cookies, or any form of user tracking on this site.
• Free Forever — Every tool is completely free with no signup required.
• Educational — Each tool includes explanations of what the data means and how to protect yourself.

How It Works

BrowserProbe uses standard browser APIs (Canvas, WebGL, AudioContext, Navigator, etc.) to detect information that any website could access. We don't exploit vulnerabilities or use any techniques that require special permissions.

The same APIs we use for detection are the same ones advertisers, analytics companies, and fingerprinting services use to track you. By showing you what's exposed, we help you make informed decisions about your browser settings and privacy tools.

Technology

BrowserProbe is built with Next.js and deployed on modern infrastructure for maximum speed. The site is fully static where possible, with client-side detection running only when you visit a tool page.
