import undetected_chromedriver as uc # Initialize an un-detectable instance of Chrome driver = uc.Chrome(options=options) Use code with caution. Method 3: Puppeteer and Playwright Stealth
If you run a standard Python Selenium script against Sannysoft, it will fail multiple tests out of the box. Below are the key strategies developers use to mask their automated browsers to achieve a green checklist. Method 1: Utilizing Selenium Stealth bot.sannysoft
It is a community-maintained diagnostic tool hosted by SannySoft. However, it is widely trusted and has been referenced in official Selenium issues and Stack Overflow solutions for nearly a decade.
First, install Selenium and a WebDriver (e.g., ChromeDriver):
Real Google Chrome browsers populate a globally available object called window.chrome which contains specific sub-properties like csi , loadTimes , and runtime . When Chrome is driven programmatically via WebDriver, this object is often missing or structurally incomplete. Bot.Sannysoft scans for these hidden features to catch unoptimized automation scripts. 3. User-Agent vs. Browser Features * 1 Answer
Maintained by developer Alexey Sannysoft, this tool is the gold standard for web scrapers, automation engineers, and cybersecurity researchers to test if their automated browsers can successfully mimic real human users. 🛡️ Why bot.sannysoft Exists
When you visit Bot.sannysoft.com with a normal browser, you will see a clean grid of green results. If you visit it with an unconfigured Selenium instance, a cascade of red alerts will trigger. Here are the primary tests it evaluates: 1. WebDriver Detection ( navigator.webdriver )

Headless mode defaults to 800x600. Fix: Explicitly set --window-size=1920,1080 AND use driver.set_window_size() .
If your headless browser fails these checks, your Selenium script might get blocked, served a CAPTCHA, or redirected to a dummy page.
