CloakBrowser

Stealth Chromium that passes every bot detection test.

Not a patched config. Not a JS injection. A real Chromium binary with fingerprints modified at the C++ source level. Antibot systems score it as a normal browser — because it is a normal browser.

Cloudflare Turnstile — 3 live tests passing (headed mode, macOS)

Drop-in Playwright/Puppeteer replacement for Python and JavaScript.
Same API, same code — just swap the import. 3 lines of code, 30 seconds to unblock.

• 66 source-level C++ patches — canvas, WebGL, audio, fonts, GPU, screen, WebRTC, network timing, automation signals, CDP input behavior
• humanize=True — human-like mouse curves, keyboard timing, and scroll patterns. One flag, behavioral detection passes
• Pro: 0.9 reCAPTCHA v3 score — human-level, server-verified
• Passes Cloudflare Turnstile, FingerprintJS, BrowserScan — tested against 30+ detection sites
• Auto-downloads the right binary — free or Pro based on your license
• pip install cloakbrowser or npm install cloakbrowser — binary auto-downloads, zero config
• Open-source wrappers — free v146 binary, Pro for latest builds

Try it now — no install needed:

docker run --rm cloakhq/cloakbrowser cloaktest

Python:

from cloakbrowser import launch

browser = launch()
page = browser.new_page()
page.goto("https://example.com")
browser.close()

JavaScript (Playwright):

import { launch } from 'cloakbrowser';

const browser = await launch();
const page = await browser.newPage();
await page.goto('https://example.com');
await browser.close();

Also works with Puppeteer: import { launch } from 'cloakbrowser/puppeteer' (details)

For sites with anti-bot protection, add a residential proxy and these flags:

browser = launch(
    proxy="http://user:pass@residential-proxy:port",  # residential IP, not datacenter
    geoip=True,       # match timezone + locale to proxy IP
    headless=False,    # some sites detect headless even with C++ patches
    humanize=True,     # human-like mouse, keyboard, scroll
)

const browser = await launch({
    proxy: 'http://user:pass@residential-proxy:port',
    geoip: true,
    headless: false,
    humanize: true,
});
