zealium 0.1.7.post2

A stealthy Chromium remote-control tool using DevTools Protocol with dynamic JS injection to evade bot detection.

Zealium

Zealium is a stealthy Chromium remote-control toolkit leveraging the Chrome DevTools Protocol with dynamic JavaScript injection to evade bot detection. It provides multi-layered anti-fingerprinting patches, human-like interaction simulation, and robust stealth capabilities for advanced browser automation.

Features

• Stealth Browser Automation: Control Chromium-based browsers (Chrome, Edge) remotely with powerful stealth techniques to bypass modern bot detection systems and CAPTCHAs.

• Dynamic JS Injection: Inject custom JavaScript patches at runtime to spoof browser fingerprints, including canvas, WebGL, audio, navigator properties, media devices, WebRTC, permissions, and more.

• Human Behavior Simulation: Simulate natural mouse movements, clicks, scrolling, and typing with randomized, non-linear patterns, hesitations, and noise to mimic real user interactions.

• Cross-Platform Support: Compatible with Windows, macOS, and Linux environments, detecting browser executables and managing user profiles seamlessly.

• Customizable Stealth Levels: Choose from multiple preset stealth configurations (low, normal, strict), or supply your own patch methods for tailored stealth strategies.

Installation

Requires Python 3.11+ and a Chromium-based browser installed.

pip install zealium

Or install dependencies manually with Poetry:

poetry install

Usage Example

from zealium import Zealium

# Launch browser with stealth
zealium = Zealium(browser="chrome", stealth_level="normal")
zealium.launch()

# Use human behavior simulator to type text
zealium.human.type_text("Hello, Zealium!")

# Interact stealthily via DevTools Protocol...

# Clean up
zealium.close()

Stealth Toolkit

Zealium includes a collection of JavaScript patches injected into the browser context to evade detection, such as:

• Spoofing navigator.webdriver and other common bot signals
• Canvas fingerprint noise and spoofing
• WebGL precision spoofing
• Overriding Function.prototype.toString
• Mocking navigator.plugins and navigator.mimeTypes
• Faking chrome.runtime
• Neutralizing WebRTC IP leaks
• Audio context fingerprint mitigation
• Mocking media devices and permissions queries
• Spoofing screen properties and Intl DateTime formatting

Stealth levels control which patches are applied:

• low: Basic evasion
• normal: Moderate stealth
• strict: Comprehensive patching

JS Injection Scripts for Stealth Patching

The injections/ folder contains multiple JavaScript scripts injected dynamically to spoof and patch browser APIs, avoiding detection by anti-bot and fingerprinting systems.

File	Purpose
audio_oscillator_patch.js	Patches AudioContext.createOscillator to add random jitter, avoiding audio fingerprinting.
canvas_noise.js	Adds subtle noise to canvas pixel data to avoid canvas fingerprint consistency.
intl_datetime_patch.js	Overrides Intl.DateTimeFormat.prototype.resolvedOptions to spoof locale and timezone data.
mock_audio_fingerprint.js	Adds small variations in audio frequency data to mask audio fingerprint patterns.
mock_chrome_runtime.js	Creates a fake chrome.runtime object to prevent detection errors in Chrome environment checks.
mock_media_devices.js	Mocks navigator.mediaDevices.enumerateDevices to simulate camera and microphone devices.
mock_navigator_connection.js	Spoofs navigator.connection properties like downlink, effectiveType, and rtt.
mock_navigator_plugins_and_mimetypes.js	Fakes navigator.plugins and navigator.mimeTypes to simulate common browser plugins.
mock_webrtc.js	Disables or spoofs WebRTC APIs like RTCPeerConnection to prevent IP leaks and fingerprinting.
navigator_properties.js	Spoofs multiple navigator properties (webdriver, plugins, languages, platform, etc.)
override_function_toString.js	Overrides Function.prototype.toString to return legitimate source code for spoofed functions.
permissions_query_patch.js	Patches navigator.permissions.query to avoid errors and spoof notification permission state.
rtc_peerconnection_patch.js	Intercepts WebRTC ICE candidates to hide local IP addresses and prevent leaks.
screen_properties.js	Spoofs screen and window size properties to mask headless or virtual environment detection.
spoof_canvas_fingerprint.js	Alters Canvas API methods to return noisy or altered pixel data to defeat canvas fingerprinting.
spoof_webgl_precision.js	Modifies WebGL precision parameters to match real hardware profiles.
webgl_spoof.js	Spoofs WebGL vendor and renderer strings to appear as common GPUs (e.g., NVIDIA).

Injecting these scripts selectively or all together via the StealthToolkit module allows fine-grained control over stealth level and evasion techniques.

Human Behavior Simulation

The HumanBehaviorSimulator mimics real user input with:

• Natural mouse movement with Bezier curves and noise
• Randomized pauses and hesitations
• Realistic typing with variable delays and error simulation
• Scrolling with randomized deltas

These features reduce detection by behavior analysis systems.

Future Improvements

Zealium will evolve into a fully independent project, removing the dependency on pychrome entirely. The future version will feature a native CDP client that communicates with Chromium via PIPE, enabling more robust, stealth-oriented automation. This transition will allow for finer orchestration of browser instances with improved isolation, performance, and undetectability—making Zealium a dedicated solution for secure and anonymous browser control.
