If your script passes all the checks on the site, it means your automation framework is mimicking a real human browser effectively. If it fails, target websites will likely block your scraper, present a CAPTCHA, or serve a "403 Forbidden" error page. Key Detection Points Checked by Bot.Sannysoft

To understand how to bypass modern bot walls, you must understand the exact parameters that Sannysoft evaluates. 1. The WebDriver Flag ( navigator.webdriver )

The tool fetches a URL and attempts to render the page using a headless Chrome browser (similar to how Google actually indexes the web now). It then provides a screenshot of what the bot sees and a list of technical data.

You can use the site to evaluate whether your automated script will be blocked by modern anti-bot technologies. To understand how to bypass modern bot walls,

No, because the page relies on external CDNs for some fonts and WebGL libraries. However, you can download the page source from GitHub (SannySoft has a public repo) and host it internally on a static server.

Headless Linux environments often lack fonts. Fix: Install common fonts on your CI runner (e.g., apt-get install fonts-liberation ).

For developers building scrapers, automating account creation, or conducting market research, the message is clear: do not assume your automation is invisible. Test it. Run your script against bot.sannysoft.com. Study which tests fail. Then patch them—one by one, property by property, flag by flag—until you see nothing but green.

A company scraping competitor prices kept getting blocked after 50 requests. Using Selenium with headless Chrome and testing against , they discovered their navigator.webdriver flag was exposed. After patching it and re-verifying with the tool, their scrape success rate jumped to 95%.
