Bot.sannysoft |top| ❲2026 Release❳

The domain sannysoft.com is the internet's premier benchmark for testing headless browser stealth and bot detection evasion.

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

Modern websites use advanced fingerprinting to block automated scripts. They look for specific browser inconsistencies to separate humans from bots.

The Sannysoft analyzer runs a battery of tests to check if your browser environment leaks its automated nature. If you are building a scraper using Puppeteer, Playwright, or Selenium, this page tells you exactly what you need to fix to avoid getting blocked. 🔬 Key Tests Performed by Sannysoft

When you visit the tool, it instantly evaluates your browser against several fingerprinting vectors: 1. User-Agent Consistency

What it checks: Ensures your User-Agent string matches the actual capabilities of the browser.

Bot giveaway: Forging a Chrome User-Agent while executing on a non-Chrome architecture. 2. WebDriver Detection What it checks: Looks for the navigator.webdriver property.

Bot giveaway: By default, automated browsers set this property to true, instantly revealing them as bots. 3. Chrome Property Leakage

What it checks: Evaluates the presence of the window.chrome object.

Bot giveaway: True Chrome browsers always have this object; many headless setups forget to emulate it. 4. Permissions & Plugins

What it checks: Queries the Permissions API and checks installed navigator plugins.

Bot giveaway: Headless browsers often return inconsistent permission states or report zero installed plugins. 5. WebGL & Canvas Fingerprinting

What it checks: Analyzes the rendering behavior of your graphics stack.

Bot giveaway: Headless environments often use software rasterizers (like SwiftShader) instead of physical GPU hardware. 🚀 How to Pass the Sannysoft Tests

Achieving a full green checklist on Sannysoft requires modifying your automation framework. Here are the most effective methods: Use Stealth Plugins

The easiest way to pass Sannysoft is by utilizing community-made evasion plugins. Puppeteer: Use puppeteer-extra-plugin-stealth. Playwright: Use playwright-stealth. Manual Evasion Techniques

If you prefer not to use plugins, you must manually patch your browser instances:

Override WebDriver: Execute a script at document start to delete or redefine navigator.webdriver. bot.sannysoft

Mock Plugins: Inject dummy data into navigator.plugins to mimic a standard desktop browser.

Match Viewports: Ensure your window dimensions and screen resolutions perfectly align. ⚠️ A Note on Modern Bot Detection

While passing the Sannysoft tests is a massive milestone for any scraping project, it does not guarantee 100% invulnerability.

Modern anti-bot solutions like Cloudflare, DataDome, and Akamai go beyond static browser fingerprints. They actively track: IP Reputation: Residential proxies are often required.

Behavioral Analysis: Mouse movements, scroll patterns, and keystroke dynamics.

TLS Fingerprinting: The way your browser constructs its initial network handshake.

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?

The website bot.sannysoft.com is a popular browser fingerprinting and anti-bot detection test used by developers and web scrapers to check if their automated scripts (like Selenium, Puppeteer, or Playwright) can be identified by a website. Core Functionality

The site performs a series of JavaScript-based checks to see if your browser exhibits "headless" or automated characteristics. If a test fails, it typically turns red, indicating that a website could likely detect you as a bot. If you are using a standard browser as a human, almost all tests should show as green. Key Detection Tests

User Agent: Checks if the string contains "HeadlessChrome" or other automation markers.

WebDriver (New): Detects the presence of the navigator.webdriver property, which is set to true by default in automated browsers.

Chrome (New): Tests for specific Chrome-only properties (like window.chrome) that are often missing in headless environments.

Permissions: Checks if the Permissions API behaves normally; bots often return inconsistent values.

Plugins & Languages: Standard browsers have a list of plugins (like PDF viewer) and specific language settings; automated instances often have empty lists.

WebGL Vendor/Renderer: Analyzes the graphics card information. Bots often leak "Mesa" or "Google SwiftShader" instead of a real hardware GPU. Common Use Cases for Developers Antibot

How to Use bot.sannysoft in Your Automation Pipeline

To make this practical, let’s walk through a step-by-step integration. Below is a Python script using Selenium that accesses bot.sannysoft and takes a screenshot for verification.

Introduction

In the rapidly evolving world of web development and quality assurance, automation is no longer a luxury—it's a necessity. Among the plethora of tools available for browser automation, Selenium stands out as the industry standard. However, even experienced developers often encounter a specific, cryptic destination when debugging or configuring their test environments: bot.sannysoft.com.

If you have ever seen a reference to "bot.sannysoft" in a tutorial, a GitHub README, or a forum thread about Selenium, you might have wondered what it is. Is it a hacking tool? A botnet? A testing ground?

In this comprehensive article, we will demystify bot.sannysoft. We will explore its purpose, how it integrates with Selenium, why it is a critical resource for QA engineers, and how to use it to validate your own headless browser setups.

Limitations and ethics

  • No mitigation is foolproof; detection scripts evolve.
  • Testing should respect website terms of service and applicable laws.
  • Do not use findings to evade protections for malicious purposes.

The Critique: It’s Not Pretty

To be fair, the user experience is lacking.

  • Interface: It is ugly. There are no graphs, no colorful dashboards, and no "Site Health Score" out of 100.
  • Language: It was originally developed by a German developer (Sanny), and while there is English support, some nuances are lost in the minimalist German efficiency of the layout.
  • Limits: It is a one-off tester. It doesn't log history or schedule automatic checks. You have to manually check your URLs.
