Stealth Chromium that passes every bot detection test. Drop-in Playwright replacement with source-level fingerprint patches.
Project description
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.
- 26 source-level C++ patches — canvas, WebGL, audio, fonts, GPU, screen, automation signals
- 0.9 reCAPTCHA v3 score — human-level, server-verified
- Passes Cloudflare Turnstile, FingerprintJS, BrowserScan — tested against 30+ detection sites
- Auto-updating binary — background update checks, always on the latest stealth build
pip install cloakbrowserornpm install cloakbrowser— binary auto-downloads, zero config- Free and open source — no subscriptions, no usage limits
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://protected-site.com") # no more blocks
browser.close()
JavaScript (Playwright):
import { launch } from 'cloakbrowser';
const browser = await launch();
const page = await browser.newPage();
await page.goto('https://protected-site.com');
await browser.close();
Also works with Puppeteer: import { launch } from 'cloakbrowser/puppeteer' (details)
Install
Python:
pip install cloakbrowser
JavaScript / Node.js:
# With Playwright
npm install cloakbrowser playwright-core
# With Puppeteer
npm install cloakbrowser puppeteer-core
On first run, the stealth Chromium binary is automatically downloaded (~200MB, cached locally).
Optional: Auto-detect timezone/locale from proxy IP:
pip install cloakbrowser[geoip]
Migrating from Playwright? 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 unchanged
⭐ Star to show support — Watch releases to get notified when new builds drop.
Latest: v0.3.5 (Chromium 145.0.7632.109)
- All 4 platforms — Linux x64, macOS arm64, macOS x64, and Windows x64 all on Chromium 145
- 26 fingerprint patches — 10 new patches since v142 (screen, device memory, audio, WebGL, auto-spoof, and more)
- Stealthy with zero flags — binary auto-generates a random fingerprint seed at startup. No configuration required
- Full stealth audit — every patch reviewed for detection vectors, multiple fixes shipped
- CDP hardening — audited and patched known automation detection vectors
- Timezone & locale from proxy IP —
launch(proxy="...", geoip=True)auto-detects timezone and locale - Playwright + Puppeteer from one package —
import from 'cloakbrowser'orimport from 'cloakbrowser/puppeteer'. Same binary, your choice of API - Persistent profiles —
launch_persistent_context()keeps cookies and localStorage across sessions, bypasses incognito detection
See the full CHANGELOG.md for details.
Why CloakBrowser?
- Config-level patches break —
playwright-stealth,undetected-chromedriver, andpuppeteer-extrainject JavaScript or tweak flags. Every Chrome update breaks them. Antibot systems detect the patches themselves. - CloakBrowser patches Chromium source code — fingerprints are modified at the C++ level, compiled into the binary. Detection sites see a real browser because it is a real browser.
- Two layers of stealth — C++ patches handle fingerprints (GPU, screen, UA, hardware reporting), while the Patchright driver defers Playwright's binding registration and randomizes internal world names. Most stealth tools only do one or the other.
- Same behavior everywhere — works identically local, in Docker, and on VPS. No environment-specific patches or config needed.
- Works with any browser automation framework — tested and passing stealth checks with Playwright, Puppeteer, Selenium, undetected-chromedriver, browser-use, Crawl4AI, and agent-browser. Just point any Chromium-based framework at the binary path.
CloakBrowser doesn't solve CAPTCHAs — it prevents them from appearing. No CAPTCHA-solving services, no proxy rotation built in — bring your own proxies, use the Playwright API you already know.

How It Works
CloakBrowser is a thin wrapper (Python + JavaScript) around a custom-built Chromium binary:
- You install →
pip install cloakbrowserornpm install cloakbrowser - First launch → binary auto-downloads for your platform (Chromium 145)
- Every launch → Playwright or Puppeteer starts with our binary + stealth args
- You write code → standard Playwright/Puppeteer API, nothing new to learn
The binary includes 26 source-level patches covering canvas, WebGL, audio, fonts, GPU, screen properties, hardware reporting, and automation signal removal.
These are compiled into the Chromium binary — not injected via JavaScript, not set via flags.
Binary downloads are verified with SHA-256 checksums to ensure integrity.
API
launch()
from cloakbrowser import launch
# Basic — headless, default stealth config
browser = launch()
# Headed mode (see the browser window)
browser = launch(headless=False)
# With proxy
browser = launch(proxy="http://user:pass@proxy:8080")
# With proxy dict (bypass, separate auth fields)
browser = launch(proxy={"server": "http://proxy:8080", "bypass": ".google.com", "username": "user", "password": "pass"})
# With extra Chrome args
browser = launch(args=["--disable-gpu"])
# With timezone and locale (sets both binary flags and Playwright context)
browser = launch(timezone="America/New_York", locale="en-US")
# Auto-detect timezone/locale from proxy IP (requires: pip install cloakbrowser[geoip])
browser = launch(proxy="http://proxy:8080", geoip=True)
# Explicit timezone/locale always win over auto-detection
browser = launch(proxy="http://proxy:8080", geoip=True, timezone="Europe/London")
# Without default stealth args (bring your own fingerprint flags)
browser = launch(stealth_args=False, args=["--fingerprint=12345"])
Returns a standard Playwright Browser object. All Playwright methods work: new_page(), new_context(), close(), etc.
launch_async()
import asyncio
from cloakbrowser import launch_async
async def main():
browser = await launch_async()
page = await browser.new_page()
await page.goto("https://example.com")
print(await page.title())
await browser.close()
asyncio.run(main())
launch_context()
Convenience function that creates browser + context in one call with user agent, viewport, locale, and timezone:
from cloakbrowser import launch_context
context = launch_context(
user_agent="Custom UA",
viewport={"width": 1920, "height": 1080},
locale="en-US",
timezone="America/New_York",
)
page = context.new_page()
page.goto("https://protected-site.com")
context.close()
launch_persistent_context()
Same as launch_context(), but with a persistent user profile. Cookies, localStorage, and cache persist across sessions. Also avoids incognito detection by services like BrowserScan.
Use this when you need to:
- Stay logged in across runs (cookies/sessions survive restarts)
- Bypass incognito detection (some sites flag empty, ephemeral profiles)
- Load Chrome extensions (extensions only work from a real user data dir)
- Build natural browsing history (cached fonts, service workers, IndexedDB accumulate over time, making the profile look more realistic)
from cloakbrowser import launch_persistent_context
# First run — creates the profile
ctx = launch_persistent_context("./my-profile", headless=False)
page = ctx.new_page()
page.goto("https://protected-site.com")
ctx.close() # profile saved
# Next run — cookies, localStorage restored automatically
ctx = launch_persistent_context("./my-profile", headless=False)
Supports all the same options as launch_context(): proxy, user_agent, viewport, locale, timezone, color_scheme, geoip.
Async version: launch_persistent_context_async().
Utility Functions
from cloakbrowser import binary_info, clear_cache, ensure_binary
# Check binary installation status
print(binary_info())
# {'version': '145.0.7632.109', 'platform': 'linux-x64', 'installed': True, ...}
# Force re-download
clear_cache()
# Pre-download binary (e.g., during Docker build)
ensure_binary()
JavaScript / Node.js API
CloakBrowser ships a TypeScript package with full type definitions. Choose Playwright or Puppeteer — same stealth binary underneath.
Playwright (default)
import { launch, launchContext, launchPersistentContext } from 'cloakbrowser';
// Basic
const browser = await launch();
// With options
const browser = await launch({
headless: false,
proxy: 'http://user:pass@proxy:8080',
args: ['--fingerprint=12345'],
timezone: 'America/New_York',
locale: 'en-US',
});
// Convenience: browser + context in one call
const context = await launchContext({
userAgent: 'Custom UA',
viewport: { width: 1920, height: 1080 },
locale: 'en-US',
timezone: 'America/New_York',
});
const page = await context.newPage();
// Persistent profile — cookies/localStorage survive restarts, avoids incognito detection
const ctx = await launchPersistentContext({
userDataDir: './chrome-profile',
headless: false,
proxy: 'http://user:pass@proxy:8080',
});
Note: Each example above is standalone — not meant to run as one block.
All Python options work in JS: stealthArgs: false to disable defaults, geoip: true to auto-detect timezone/locale from proxy IP.
Puppeteer
Note: The Playwright wrapper is recommended for sites with reCAPTCHA Enterprise. Puppeteer's CDP protocol leaks automation signals that reCAPTCHA Enterprise can detect, causing intermittent 403 errors. This is a known Puppeteer limitation, not specific to CloakBrowser. Use Playwright for best results.
import { launch } from 'cloakbrowser/puppeteer';
const browser = await launch({ headless: true });
const page = await browser.newPage();
await page.goto('https://example.com');
await browser.close();
Utility Functions (JS)
import { ensureBinary, clearCache, binaryInfo } from 'cloakbrowser';
// Pre-download binary (e.g., during Docker build)
await ensureBinary();
// Check installation status
console.log(binaryInfo());
// Force re-download
clearCache();

Fingerprint Management
The binary is stealthy by default — no flags needed. It auto-generates a random fingerprint seed at startup and spoofs all detectable values (GPU, hardware specs, screen dimensions, canvas, WebGL, audio, fonts). Every launch produces a fresh, coherent identity.
How fingerprinting works:
| Scenario | What happens |
|---|---|
| No flags | Random seed auto-generated at startup. GPU, screen, hardware specs, and all noise patches are spoofed automatically. Fresh identity each launch. |
--fingerprint=seed |
Deterministic identity from the seed. Same seed = same fingerprint across launches. Use this for session persistence (returning visitor). |
--fingerprint=seed + explicit flags |
Explicit flags override individual auto-generated values. The seed fills in everything else. |
The binary detects its platform at compile time — a macOS binary reports as macOS with Apple GPU, a Linux binary reports as Linux with NVIDIA GPU. The wrapper overrides this on Linux by passing --fingerprint-platform=windows, so sessions appear as Windows desktops (more common fingerprint, harder to cluster). Use --fingerprint-platform for cross-platform spoofing when running the binary directly.
Tip: Use a fixed seed when revisiting the same site. A random seed makes every session look like a different device — which can be suspicious when hitting the same site repeatedly from the same IP. For reCAPTCHA v3 Enterprise and similar scoring systems, a fixed seed produces a consistent fingerprint across sessions, making you look like a returning visitor:
browser = launch(args=["--fingerprint=12345"])const browser = await launch({ args: ['--fingerprint=12345'] });
Default Fingerprint & All Flags (click to expand)
Default Fingerprint
Every launch() call sets these automatically. The wrapper applies platform-aware defaults — on Linux it spoofs as Windows for a more common fingerprint, on macOS it runs as a native Mac browser:
| Flag | Linux/Windows Default | macOS Default | Controls |
|---|---|---|---|
--fingerprint |
Random (10000–99999) | Random (10000–99999) | Master seed for canvas, WebGL, audio, fonts, client rects |
--fingerprint-platform |
windows |
macos |
navigator.platform, User-Agent OS, GPU pool selection |
--fingerprint-gpu-vendor |
NVIDIA Corporation |
Google Inc. (Apple) |
WebGL UNMASKED_VENDOR_WEBGL |
--fingerprint-gpu-renderer |
NVIDIA GeForce RTX 3070 |
ANGLE (Apple, ANGLE Metal Renderer: Apple M3, Unspecified Version) |
WebGL UNMASKED_RENDERER_WEBGL |
The binary auto-generates hardware concurrency (8), device memory (8), and screen dimensions (1920x1080 on Windows/Linux, 1440x900 on macOS) from the seed. Override with explicit flags if needed.
Using the binary directly? It works out of the box with zero flags — the binary auto-spoofs everything. Pass
--fingerprint=seedfor a persistent identity, or use explicit flags like--fingerprint-gpu-rendererto override any auto-generated value.
Production tip: For better stealth at scale, pass your own GPU, screen, and hardware values instead of relying on defaults. Custom parameters make your sessions harder to cluster by anti-bot systems that look for uniform fingerprint profiles.
Additional Flags
Supported by the binary but not set by default — pass via args to customize:
| Flag | Controls |
|---|---|
--fingerprint-hardware-concurrency |
navigator.hardwareConcurrency (auto-generated: 8) |
--fingerprint-device-memory |
navigator.deviceMemory in GB (auto-generated: 8) |
--fingerprint-screen-width |
Screen width (auto-generated: 1920 Win/Linux, 1440 macOS) |
--fingerprint-screen-height |
Screen height (auto-generated: 1080 Win/Linux, 900 macOS) |
--fingerprint-brand |
Browser brand: Chrome, Edge, Opera, Vivaldi |
--fingerprint-brand-version |
Brand version (UA + Client Hints) |
--fingerprint-platform-version |
Client Hints platform version |
--fingerprint-location |
Geolocation coordinates |
--fingerprint-timezone |
Timezone (e.g. America/New_York) |
--fingerprint-taskbar-height |
Override taskbar height (binary defaults: Win=48, Mac=95, Linux=0) |
--fingerprint-fonts-dir |
Path to cross-platform font directory |
--enable-blink-features=FakeShadowRoot |
Access closed shadow DOM elements |
Note: All stealth tests were verified with the default fingerprint config above. Changing these flags may affect detection results — test your configuration before using in production.
Examples
# Pin a seed for a persistent identity
browser = launch(args=["--fingerprint=42069"])
# Full control — disable defaults, set everything yourself
browser = launch(stealth_args=False, args=[
"--fingerprint=42069",
"--fingerprint-platform=windows",
"--fingerprint-gpu-vendor=NVIDIA Corporation",
"--fingerprint-gpu-renderer=NVIDIA GeForce RTX 3070",
])
# Override GPU to look like a different machine
browser = launch(args=[
"--fingerprint-gpu-vendor=Intel Inc.",
"--fingerprint-gpu-renderer=Intel Iris OpenGL Engine",
])

Docker
Pre-built image on Docker Hub — no install, no setup:
# Run the stealth test suite
docker run --rm cloakhq/cloakbrowser cloaktest
# Run your own script
docker run --rm cloakhq/cloakbrowser python -c "
from cloakbrowser import launch
browser = launch()
page = browser.new_page()
page.goto('https://example.com')
print(page.title())
browser.close()
"
# With a proxy
docker run --rm cloakhq/cloakbrowser python -c "
from cloakbrowser import launch
browser = launch(proxy='http://user:pass@proxy:8080')
page = browser.new_page()
page.goto('https://example.com')
print(page.title())
browser.close()
"
To extend with your own script:
FROM cloakhq/cloakbrowser
COPY your_script.py /app/
CMD ["python", "your_script.py"]
Building from source — a Dockerfile is also included if you prefer to build your own image:
docker build -t cloakbrowser .
CloakBrowser works identically local, in Docker, and on VPS. No environment-specific config needed.
Note: If you run CloakBrowser inside a web server with uvloop (e.g., uvicorn[standard]), use --loop asyncio to avoid subprocess pipe hangs.
Troubleshooting
Still getting blocked on aggressive sites (DataDome, Turnstile)?
Some sites detect headless mode even with our C++ patches. Run in headed mode with a virtual display:
# Install Xvfb (virtual framebuffer)
sudo apt install xvfb
# Start virtual display
Xvfb :99 -screen 0 1920x1080x24 &
export DISPLAY=:99
from cloakbrowser import launch
# Headed mode + residential proxy for maximum stealth
browser = launch(headless=False, proxy="http://your-residential-proxy:port")
page = browser.new_page()
page.goto("https://heavily-protected-site.com") # passes DataDome, etc.
browser.close()
This runs a real headed browser rendered on a virtual display — no physical monitor needed. Combined with a residential proxy, this passes even the most aggressive detection services. Datacenter IPs are often flagged by IP reputation regardless of browser fingerprint — a residential proxy makes the difference.
Reddit or similar sites show CAPTCHA / "Prove your humanity"
Some sites (notably Reddit homepage) use HTTP/2 fingerprinting that detects Playwright's connection layer. Pass --disable-http2 to fall back to HTTP/1.1:
browser = launch(args=["--disable-http2"])
const browser = await launch({ args: ['--disable-http2'] });
Only use this flag for sites that require it — most sites work fine with HTTP/2.
Something not working? Make sure you're on the latest version Older versions may use outdated stealth args or download an older binary:
pip install -U cloakbrowser # Python
npm install cloakbrowser@latest # JavaScript
docker pull cloakhq/cloakbrowser:latest # Docker
Binary download fails / timeout Set a custom download URL or use a local binary:
export CLOAKBROWSER_BINARY_PATH=/path/to/your/chrome
New update broke something? Roll back to the previous version
When auto-update downloads a newer binary, the previous version stays in ~/.cloakbrowser/. Point CLOAKBROWSER_BINARY_PATH to the older cached binary:
# Linux
export CLOAKBROWSER_BINARY_PATH=~/.cloakbrowser/chromium-145.0.7632.109/chrome
# macOS
export CLOAKBROWSER_BINARY_PATH=~/.cloakbrowser/chromium-145.0.7632.109/Chromium.app/Contents/MacOS/Chromium
# Windows
set CLOAKBROWSER_BINARY_PATH=%USERPROFILE%\.cloakbrowser\chromium-145.0.7632.109\chrome.exe
macOS: "App is damaged" or Gatekeeper blocks launch The binary is ad-hoc signed. macOS quarantines downloaded files. Run once to clear it:
xattr -cr ~/.cloakbrowser/chromium-*/Chromium.app
"playwright install" vs CloakBrowser binary
You do NOT need playwright install chromium. CloakBrowser downloads its own binary. You only need Playwright's system deps:
patchright install-deps chromium
macOS: Blocked on some sites that pass on Linux
The macOS fingerprint profile has known inconsistencies that aggressive bot detection catches. If a site blocks you on macOS but works on Linux, switch to a Windows fingerprint profile by passing stealth_args=False and manually setting --fingerprint-platform=windows with matching GPU flags (see Fingerprint Management for the full flag list).
Site detects incognito / private browsing mode
By default, launch() opens an incognito context. Some sites (like BrowserScan) detect this. Use launch_persistent_context() instead — it runs with a real user profile, so incognito detection passes:
from cloakbrowser import launch_persistent_context
ctx = launch_persistent_context("./my-profile", headless=False)
page = ctx.new_page()
import { launchPersistentContext } from 'cloakbrowser';
const ctx = await launchPersistentContext({
userDataDir: './my-profile',
headless: false,
});
This also gives you cookie and localStorage persistence across sessions.
reCAPTCHA v3 scores are low (0.1–0.3)
Avoid page.wait_for_timeout() — it sends CDP protocol commands that reCAPTCHA detects. Use native sleep instead:
# Bad — sends CDP commands, reCAPTCHA detects this
page.wait_for_timeout(3000)
# Good — invisible to the browser
import time
time.sleep(3)
// Bad — sends CDP commands
await page.waitForTimeout(3000);
// Good — invisible to the browser
await new Promise(r => setTimeout(r, 3000));
Other tips for maximizing reCAPTCHA scores:
- Use Playwright, not Puppeteer — Puppeteer sends more CDP protocol traffic that reCAPTCHA detects (details)
- Use residential proxies — datacenter IPs are flagged by IP reputation, not browser fingerprint
- Spend 15+ seconds on the page before triggering reCAPTCHA — short visits score lower
- Space out requests — back-to-back
grecaptcha.execute()calls from the same session get penalized. Wait 30+ seconds between pages with reCAPTCHA - Use a fixed fingerprint seed for consistent device identity across sessions (see Fingerprint Management)
- Use
page.type()instead ofpage.fill()for form filling —fill()sets values directly without keyboard events, which reCAPTCHA's behavioral analysis flags.type()with a delay simulates real keystrokes:page.type("#email", "user@example.com", delay=50)
- Minimize
page.evaluate()calls before the reCAPTCHA check fires — each one sends CDP traffic
FAQ
Q: Is this legal? A: CloakBrowser is a browser built on open-source Chromium. We do not condone illegal use. Automating systems without authorization, credential stuffing, and account creation abuse are expressly prohibited. See BINARY-LICENSE.md for full terms.
Q: How is this different from Camoufox? A: Camoufox patches Firefox. We patch Chromium. Chromium means native Playwright support, larger ecosystem, and TLS fingerprints that match real Chrome. Camoufox returned in early 2026 but is in unstable beta — CloakBrowser is production-ready.
Q: Will detection sites eventually catch this? A: Possibly. Bot detection is an arms race. Source-level patches are harder to detect than config-level patches, but not impossible. We actively monitor and update when detection evolves.
Q: Can I use my own proxy?
A: Yes. Pass proxy="http://user:pass@host:port" to launch().
