CloakBrowser is a thin wrapper (Python + JavaScript) around a custom-built Chromium binary:

|
|
|
|
|
|
1. **You install** → `pip install cloakbrowser` or `npm install cloakbrowser`
|
|
|
|

2. **First launch** → binary auto-downloads for your platform (Chromium 145)

2. **First launch** → binary auto-downloads for your platform (Chromium 146)
|
|
|
|
|
3. **Every launch** → Playwright or Puppeteer starts with our binary + stealth args
|
|
|
|
|
4. **You write code** → standard Playwright/Puppeteer API, nothing new to learn
|
|
|
|
|
|
|

|
|
The binary includes 48 source-level patches covering canvas, WebGL, audio, fonts, GPU, screen properties, WebRTC, network timing, hardware reporting, automation signal removal, and CDP input behavior mimicking.

Install a specific wrapper version to downgrade both the wrapper and the binary it downloads:
|
|
|
|
|
```bash
|

|
|
pip install cloakbrowser==0.3.11 # Python
|
|
|
|
|
npm install cloakbrowser@0.3.11 # JavaScript
