Browser JS Dumper

This is a work in progress!

Live Tool: https://redrrx.github.io/browser-js-dumper/

A specialized tool to dump and diff the entire JavaScript global scope. Built for reverse engineers and anti-detect developers who need to see exactly what a browser is showing to the web.

Why use this?

• Spot Anti-Bot Triggers: Instantly find "red flags" (like navigator.webdriver, cdc_ strings, or CDP artifacts) that trigger Cloudflare, DataDome, or Akamai.
• Diff Environments: Export a JSON snapshot of a "clean" vanilla Chrome environment and import it into your custom "stealth" build to find discrepancies in the global surface.
• Leak Hunting: See every property, prototype, and object injected by extensions, automation frameworks, or custom browsers.
• Offline Analysis: Capture a snapshot from a protected environment and analyze the object tree locally without staying connected to the target.

Quick Workflow

1. Dump your current environment.
2. Export the JSON.
3. Import it later (or on a different browser) to compare object structures and identify unique fingerprints.

Known Issues

• Firefox (No DRM): requires installation to be finished for the dumper to initialize.
• Type Mismatch: Few inconsistencies between specific browser values during serialization on some environments.

Tested On

• Chromium-based (Chrome, Brave, Edge, etc.)
• Firefox
