Bot.sannysoft
If you pass bot.sannysoft.com fully, your bot looks very human-like to basic detection scripts.
Would you like a sample evasion script or a Dockerized bot that passes this test?
The website bot.sannysoft.com is a widely used bot-detection testing tool used by developers and security researchers to check how "stealthy" their web automation scripts are. Core Purpose
It analyzes your browser's environment to see if it can distinguish between a real human user and an automated bot. When you visit the site, it runs a series of tests to check for "leaks"—technical signs that indicate automation tools like Puppeteer, Selenium, or Playwright are in use. Key Detection Tests
The site checks various attributes that bots often fail to mimic correctly:
User-Agent: Ensures the browser identity string is consistent with its actual behavior.
WebDriver Flag: Detects if the navigator.webdriver property is set to true, which is a default for most automation tools. bot.sannysoft
Chrome Runtime: Looks for the window.chrome property, which is often missing or different in headless browsers.
Plugins & Languages: Verifies that standard browser plugins and language settings are present and not empty.
Hardware Fingerprinting: Checks attributes like screen resolution, device memory, and WebGL signatures to see if they match a realistic user profile. Why Developers Use It
Benchmarking Stealth Plugins: Developers use it to test the effectiveness of tools like puppeteer-extra-plugin-stealth or playwright-stealth.
Debugging Blocks: If a scraper is being blocked by anti-bot services like Cloudflare or Akamai, Sannysoft helps identify which specific browser property is giving the bot away.
Comparison: It is often used alongside other detection sites like Pixelscan or bot.incolumitas.com for a comprehensive audit of a browser's fingerprint. If you pass bot
Are you trying to bypass detection with a specific tool, or are you auditing a browser for security purposes?

Bot.sannysoft.com is a premier benchmarking tool used by developers to test the stealth of browser automation scripts (like Selenium, Puppeteer, or Playwright) against anti-bot detection systems.
The site analyzes various browser attributes—such as JavaScript execution, hardware fingerprints, and rendering behaviors—to flag automated sessions. Key Detection Features
The "prepare feature" likely refers to the specific browser attributes or "signals" that the site checks to identify bots. Key tests include: Would you like a sample evasion script or
User-Agent: Checks for inconsistencies between the browser's reported identity and its actual execution environment.
Webdriver Presence: Specifically looks for the navigator.webdriver flag, which is often set to true by default in automated browsers.
Hardware Fingerprinting: Examines Canvas, WebGL, and AudioContext fingerprints to see if they match real-world hardware profiles.
Hairline Feature: A specific test for the presence of a "hairline" (fractional pixel rendering), which is often missing or incorrectly handled in headless browser environments.
Permissions & Plugins: Detects if browser permissions (like notifications) or the list of installed plugins appear "spoofed" or characteristic of a bot.
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.
Why? Headless Chrome has a limited WebGL implementation.
Fix: Consider running in non-headless mode for critical visual tests, or use a renderer like xvfb on Linux.
The SannySoft page provides a real-time log of the User Agent, IP address, and browser capabilities. If your WebDriver is misconfigured (e.g., using the wrong binary path), the output on bot.sannysoft will reveal inconsistencies immediately.
