CloakBrowser

What it is

CloakBrowser — stealth Chromium fork that passes anti-bot detection. Drop-in replacement for Playwright/Puppeteer.

Instead of JS injection or config tweaks, it applies 58 C++ source-level patches to the browser binary, so fingerprint spoofing happens at the engine level.

What it spoofs

• Canvas and WebGL rendering output
• Audio context fingerprint
• GPU/graphics hardware reporting
• Screen and display properties
• WebRTC IP leakage
• Network timing signatures
• Removes automation signals (navigator.webdriver, etc.)

Auto-generates random fingerprint seeds on each launch → fresh identity while keeping internal coherence across browser APIs.

Performance

• reCAPTCHA v3 score: 0.9 (vs 0.1 on standard Playwright)
• Passes Cloudflare Turnstile, FingerprintJS, and 30+ detection services

Usage

pip install cloakbrowser
# or
npm install cloakbrowser

Binary (~200MB) downloads on first run. Works as a drop-in for Playwright scripts.

Features

• Humanize mode — realistic mouse curves, keyboard timing, scroll patterns
• Persistent profiles — cookies and localStorage across sessions
• Proxy support — HTTP and SOCKS5, with geo-IP awareness
• Runs on Linux, macOS, Windows
