: Looks for the window.chrome property, which is often missing or different in headless browsers.
If you'd like to refine your setup further, consider your (Python, Node.js), framework (Selenium, Playwright, Puppeteer), and the specific error or red flag on the Sannysoft dashboard for a tailored solution. Share public link
Understanding Bot.sannysoft: The Ultimate Benchmark for Anti-Bot Evasion and Browser Fingerprinting
: Your instance is leaking automation artifacts (like WebDriver: True ), which will likely lead to blocks or CAPTCHAs on protected sites.
If you're going the DIY route, you must manually set browser arguments like --disable-blink-features=AutomationControlled to hide your automation status. The Bottom Line bot.sannysoft
The page includes timestamps and load-time metrics. By running bot.sannysoft before and after a server update, you can benchmark rendering speed in a controlled environment.
Modern anti-bot solutions like Cloudflare, DataDome, and Akamai go beyond static browser fingerprints. They actively track: Residential proxies are often required.
Sannysoft is your first line of defense to ensure your browser looks human at the code level before you tackle behavioral hurdles. js to help your scraper pass the Sannysoft tests?
, CPU architecture, and hardware concurrency to see if they match expected real-world values. Chrome Features : Looks for the window
Even a perfectly configured stealth browser will get banned if it makes 1,000 requests per minute from a single IP address. Pair your stealth setup with rotating residential proxies to distribute your request origin.
You can use the site to evaluate whether your automated script will be blocked by modern anti-bot technologies.
Enter . It doesn't look like much. In fact, the design is aggressively utilitarian—white background, black text, blue links. It looks like a webpage from 2003. But don't let the retro aesthetic fool you; this tool is arguably one of the most important reality checks a technical SEO has in their arsenal.
When building data scrapers, automation tools, or testing suites using software like Selenium , Puppeteer , or Playwright, websites frequently block access via Cloudflare, Akamai, or PerimeterX. The Sannysoft bot test acts as a mirror, showing you exactly what security systems see when your automated browser lands on a page. Why Automated Browsers Get Blocked Instantly If you're going the DIY route, you must
# Wait for all dynamic content to load time.sleep(3)
: Since these tools often run in "headless" mode (no visible window), developers typically program the bot to take a screenshot of the results page for manual review. How to Pass the Sannysoft Tests
The most fundamental test checks for the existence of navigator.webdriver . By default, W3C standards require standard automation frameworks to set this property to true . If the Sannysoft tool finds this flag present, the test fails immediately. 2. Advanced Window Properties and CDP Artifacts
The domain is the internet's premier benchmark for testing headless browser stealth and bot detection evasion.
