Puppeteer Stealth is puppeteer plugin that fortifies headles browser for web scraping. This makes detection of puppeteer scrapers more difficult allowing to scrape targets which use headless browser detection techniques.

Puppeteer-stealth does this by applying various javascript patches to cover up traces of headless browser presence in the web scraping browser's environment.

nodriver is a Python library for browser automation that communicates directly with the browser via the Chrome DevTools Protocol (CDP), without relying on Selenium or chromedriver. It is the successor to undetected-chromedriver, created by the same author, and is designed from the ground up to be undetectable by anti-bot systems.

Key advantages over traditional browser automation:

No chromedriver dependency Communicates directly with Chrome/Chromium via CDP websocket, eliminating the most common detection vector (chromedriver fingerprint).
Undetectable by default Does not set the navigator.webdriver flag, does not inject automation-related JavaScript, and avoids CDP detection patterns that anti-bot systems look for.
Fast and lightweight Without the Selenium/WebDriver protocol overhead, nodriver is significantly faster at launching browsers and executing commands.
Async-first Built entirely on Python's asyncio, enabling efficient concurrent browser automation.
Simple API Clean, Pythonic API that is easier to use than raw CDP or Selenium.

nodriver is particularly useful for scraping websites protected by advanced anti-bot systems like Cloudflare, DataDome, or PerimeterX, where standard Selenium or Playwright setups get detected and blocked.

Example Use

```javascript const puppeteer = require('puppeteer-extra') // add stealth plugin and use defaults (all evasion techniques) const StealthPlugin = require('puppeteer-extra-plugin-stealth') puppeteer.use(StealthPlugin()) // puppeteer usage as normal puppeteer.launch({ headless: true }).then(async browser => { console.log('Running tests..') const page = await browser.newPage() await page.goto('https://bot.sannysoft.com') await page.waitForTimeout(5000) await page.screenshot({ path: 'result.png', fullPage: true }) await browser.close() console.log("success - check the result.png screenshot") }) ```

```python import nodriver as uc import asyncio async def main(): # Launch browser - undetected by default browser = await uc.start() # Open a new tab and navigate tab = await browser.get("https://example.com") # Wait for an element and interact with it search_box = await tab.find("input[name='q']") await search_box.send_keys("web scraping") # Click a button button = await tab.find("button[type='submit']") await button.click() # Wait for navigation and extract content await tab.wait_for("div.results") results = await tab.query_selector_all("div.result") for result in results: title = await result.query_selector("h3") print(await title.get_text()) # Take a screenshot await tab.save_screenshot("results.png") browser.stop() asyncio.run(main()) ```
