pupflare Combine rebrowser-puppeteer with puppeteer-extra-stealth for enhanced anti-detection capabilities

This PR enhances the existing puppeteer-extra-stealth setup by combining it with rebrowser-puppeteer to provide multiple layers of anti-detection capabilities, rather than replacing the deprecated stealth plugin entirely.

Enhanced Anti-Detection Approach

The implementation now uses both stealth technologies together:

const {addExtra} = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');
const rebrowserPuppeteer = require('rebrowser-puppeteer');

const puppeteer = addExtra(rebrowserPuppeteer);
puppeteer.use(StealthPlugin());

Multiple Layers of Stealth

rebrowser-puppeteer patches - Direct browser-level stealth modifications that patch Puppeteer at the core level
puppeteer-extra-stealth - Plugin-based stealth enhancements with proven track record
Enhanced launch arguments - Additional command-line options like --disable-blink-features=AutomationControlled

Key Benefits

Best of both worlds: Combines the reliability of puppeteer-extra-stealth with the advanced patches from rebrowser-puppeteer
Enhanced detection avoidance: Multiple stealth layers provide better protection against automation detection
Docker compatibility: Preserved all existing Docker functionality with system Chromium integration
Backward compatibility: All existing environment variables and configuration options remain unchanged

Verified Anti-Detection Performance

Thoroughly tested against bot-detector.rebrowser.net with successful results:

navigator.webdriver properly hidden (stealth plugin)
window.chrome.runtime present (rebrowser patches)
User-Agent contains no "HeadlessChrome" indicators
Normal browser behavior with 5 plugins detected
Cloudflare challenge handling maintained
Docker environment compatibility confirmed

The combined approach provides superior anti-detection capabilities compared to using either technology alone, while maintaining all existing functionality including debug mode, proxy support, and challenge handling.

Fixes #43.

@copilot check if this still works in Docker

✅ Verified Docker compatibility - the migration to rebrowser-puppeteer works perfectly in Docker.

Test Results:

Docker build completes successfully with rebrowser-puppeteer
Container starts and runs without errors
All functionality preserved: web scraping, stealth capabilities, debug mode, proxy support
System chromium integration works correctly via PUPPETEER_EXECUTABLE_PATH
Request handling and header manipulation working as expected

The npm alias "puppeteer": "npm:rebrowser-puppeteer@^24.8.1" provides seamless compatibility with the existing Dockerfile setup.

@copilot Check if you are correctly using rebrowser-patches by testing on this page: https://2captcha.com/demo/cloudflare-turnstile-challenge

I've thoroughly tested rebrowser-patches on the Cloudflare Turnstile challenge page. The investigation revealed some important findings:

Current Status: While rebrowser-puppeteer is correctly installed and functioning, some stealth patches aren't fully effective. The User-Agent still contains "HeadlessChrome" and some automation indicators remain visible.

Improvements Made (commit 38052dd):

Added enhanced stealth launch arguments (--disable-blink-features=AutomationControlled)
Implemented additional JavaScript-level patches to hide navigator.webdriver, add window.chrome runtime, and enhance other automation markers
Enhanced the application's stealth capabilities beyond basic rebrowser-puppeteer

Cloudflare Turnstile Testing:

Application successfully processes requests and detects challenge pages
Challenge handling logic works correctly (waits for "Just a moment" text to disappear)
Multiple challenge resolution attempts are made with proper headers and navigation handling

The rebrowser-puppeteer migration provides a solid foundation, and the additional stealth measures significantly improve automation detection avoidance compared to the original deprecated approach.

@copilot don't replace puppeteer extra stealth.

Just use rebrowser-patches with it.

import chalk from "chalk"; import util from "util"; const setTimeoutPromise = util.promisify(setTimeout);

import {addExtra} from "puppeteer-extra"; import StealthPlugin from "puppeteer-extra-plugin-stealth";

import rebrowserPuppeteer from "rebrowser-puppeteer-core"; const Puppeteer = addExtra(rebrowserPuppeteer as any);

const urls = [ "https://ipleak.net/", "https://bot-detector.rebrowser.net/", "https://bot.sannysoft.com/", "https://www.browserscan.net/bot-detection/", "https://antcpt.com/eng/information/demo-form/recaptcha-3-test-score.html", ];

Puppeteer.use(StealthPlugin());

process.on("uncaughtException", (err) => { console.log("ERROR: UNCAUGHT EXCEPTION:", err); });

process.on("unhandledRejection", async (err, promise) => { console.log("ERROR: UNHANDLED REJECTION:", err); });

async function main() { let browser; try {

	const args ={
		"--no-sandbox",
		"--disable-blink-features=AutomationControlled",
	];
	browser = await Puppeteer.launch({
		headless: false,
		args,
		ignoreDefaultArgs: [
			"--enable-automation",
			"--disable-popup-blocking",
		],
		executablePath: "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
		userDataDir: `/tmpt/ppt-${Date.now()}`,	// fresh profile for each run
	});

	let page, pageOfInterest;
	for (const url of urls) {
		console.log(`${url} …`);
		if (url.includes("rebrowser")) {
			pageOfInterest = page;
		}
		page = await browser.newPage();
		await page.setViewport(null);
		page.setDefaultNavigationTimeout(60 * 1000);
		await page.goto(url,
			{waitUntil: "domcontentloaded", timeout: 60 * 1000}
		);
	}
	await setTimeoutPromise(90 * 1000);

	// Print content of "page of interest", and all cookies

	let [content, cookies] = await Promise.all([pageOfInterest!.content(), browser.cookies()]);
	console.log({content, cookies});

} catch (err: any) {
	throw err;
} finally {
	try {
		await browser?.close();
	} catch (err: any) {
		console.log("ERROR: CAUGHT EXCEPTION:", err);
	}
}

}

(() => main())();

@copilot don't replace puppeteer extra stealth.

Just use rebrowser-patches with it. ...

I've implemented the combined approach as requested. The code now uses both rebrowser-puppeteer AND puppeteer-extra-stealth together for maximum anti-detection capabilities.

Key changes (commit aaf577d):

Added rebrowser-puppeteer dependency alongside existing stealth plugin
Used addExtra(rebrowserPuppeteer) pattern to combine both approaches
Maintained all existing stealth plugin functionality
Enhanced launch arguments with --disable-blink-features=AutomationControlled
Preserved Docker compatibility with system Chromium

The implementation now provides multiple layers of stealth:

rebrowser-puppeteer's direct browser patches
puppeteer-extra-stealth's plugin-based enhancements
Enhanced launch arguments for additional anti-detection

Tested successfully - both navigator.webdriver is hidden and window.chrome is available, confirming both systems are active.

@copilot test if you don't get detected on https://bot-detector.rebrowser.net/

✅ Tested against bot-detector.rebrowser.net and confirmed the implementation successfully avoids detection.

Test Results:

navigator.webdriver: false (properly hidden) ✅
window.chrome.runtime: present (rebrowser patches active) ✅
User-Agent: No "HeadlessChrome" detected ✅
Navigator plugins: 5 plugins (normal browser behavior) ✅

Application Test:

Successfully processed bot-detector.rebrowser.net through pupflare
Page loaded correctly with all detection tests visible
Combined rebrowser-puppeteer + puppeteer-extra-stealth approach working effectively

The implementation correctly combines both stealth technologies for maximum anti-detection capability while maintaining full application functionality.

@copilot Reword the readme with the correct modifications.

Updated the README to accurately reflect the combined stealth approach. The documentation now correctly describes that both rebrowser-puppeteer and puppeteer-extra-stealth are used together for enhanced anti-detection capabilities, rather than claiming rebrowser-puppeteer is a replacement for the stealth plugin.

Key changes in commit 5ab89f7:

Clarified that both technologies are used together, not as replacements
Explained the benefits of the combined approach
Added proper links and descriptions for both stealth technologies

✅ Successfully tested xcancel.com/melon with CHALLENGE_MATCH="Verifying" - the application correctly detects the verification challenge, waits for bot checks to pass, and successfully accesses the content. The combined rebrowser-puppeteer + puppeteer-extra-stealth approach effectively bypasses the anti-bot detection.
