Three lines to stealth
Same Playwright/Puppeteer API you already know. Just swap the import.
from cloakbrowser import launch
browser = launch()
page = browser.new_page()
page.goto("https://protected-site.com") # no more blocks
browser.close()import { launch } from 'cloakbrowser';
const browser = await launch();
const page = await browser.newPage();
await page.goto('https://protected-site.com');
await browser.close();import { launch } from 'cloakbrowser/puppeteer';
const browser = await launch({ headless: true });
const page = await browser.newPage();
await page.goto('https://protected-site.com');
await browser.close();Migrating? One line change.
- from playwright.sync_api import sync_playwright
- pw = sync_playwright().start()
- browser = pw.chromium.launch()
+ from cloakbrowser import launch
+ browser = launch()
page = browser.new_page()
page.goto("https://example.com")
# ... rest of your code works unchangedWhy CloakBrowser?
Config-level stealth breaks every Chrome update. We patch Chromium itself.
Source-level patches
22 C++ patches compiled into the Chromium binary. Not JavaScript injection, not config flags. Canvas, WebGL, audio, fonts, GPU — all modified before compilation. Detection sites see a real browser because it is a real browser.
Two layers of stealth
C++ patches handle fingerprints (GPU, screen, UA, voices, media devices). The Patchright driver eliminates CDP automation leaks (Runtime.enable, Chrome flags, console detection). Most tools only do one or the other.
Drop-in replacement
Same Playwright API. Same Puppeteer API. No new abstractions, no CAPTCHA-solving services, no new SDK to learn. Change your import, keep your code.

How it works
A thin wrapper around a custom-built Chromium binary.
Install
pip install cloakbrowser or npm install cloakbrowser
First launch
Binary auto-downloads for your platform (~200MB, cached locally)
Every launch
Playwright or Puppeteer starts with our binary + stealth args
Write code
Standard Playwright/Puppeteer API — nothing new to learn
22 source-level patches
Compiled into the binary — not injected via JavaScript, not set via flags.
v145 — Next-level stealth
Chromium 145 with significant upgrades across the board.
