Trace Guard

Trace Guard silently intercepts HTTP requests to inject behavioral telemetry and block bots—specifically targeting agentic browsers driven by VLMs (Claude Computer Use, Playwright, Puppeteer). It relies on physical truths that cannot be spoofed.

Tech Stack

Node.jsTypeScriptEdge RuntimeCDP Detection
02

Core Engine

Hardware Truth Engine (v3.7.0)

03

The Challenge

Modern AI agents (VLMs) take screenshots and calculate pixel coordinates to click directly, bypassing traditional behavioral math because they don't physically move mice.

04

The Solution

Implemented 'Pre-Flight Teleport Traps' and physiological analysis like Acceleration Asymmetry—detecting the biomechanical difference in how humans push upward vs. downward.

05

Key Innovations

VLM Jamming, Ghost Mouse Payload detection, and Native Prototype Integrity checks to neutralize stealth plugins hiding navigator.webdriver.

06

Deployment

A zero-configuration 'setupHook' that globally patches http.createServer or integrates natively as Next.js Edge Middleware.
