Free Diagnostic Tools

Three tools that work together — diagnose detection risk at the network, application, and economic layers. All probes use public W3C browser APIs. Nothing sent to a server.

IP Checker

Network-layer detection

Detect your public IP, ASN, geolocation, and classification (mobile carrier / residential / datacenter / VPN). Includes WebRTC leak test.

Browser Fingerprint Checker

Application-layer detection

Probe your browser via real W3C APIs: canvas hash, WebGL renderer, AudioContext signature, installed fonts, automation markers (webdriver, headless).

Why a Diagnostic Suite?

Anti-bot detection runs in multiple layers simultaneously. Improving just one layer (only proxy or only fingerprint) leaves the others exposed.

Network Layer

ASN, IP reputation, geo, WebRTC leaks — checked before any JavaScript runs. Datacenter IPs auto-flagged.

→ IP Checker

Application Layer

Canvas, WebGL, audio, fonts, automation flags — checked via JavaScript once page loads. Catches headless browsers.

→ Fingerprint Checker
