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?
This is the most basic check. By default, automated browsers set navigator.webdriver to true . Human browsers leave this value false or undefined. If Sannysoft detects true , your bot is exposed instantly. 2. Chrome Headless Signatures
In this comprehensive article, we will demystify . 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.
Verifying if reported screen resolution, color depth, or CPU cores match what a real device would typically show. 🛠️ Common Use Cases bot.sannysoft

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
Next time you configure a Selenium WebDriver, headless or not, make it a habit to navigate to https://bot.sannysoft.com and take a screenshot. Let the green lights guide your way to robust, resilient automation. Sannysoft is your first line of defense to
For those running multiple CLI coding agents—such as Claude Code, Codex CLI, or Gemini CLI—there is even a dedicated toolkit called browser-harness-kit that wires all of them to a shared stealth Chromium. The goal is to ensure "every agent drives a real headed Chromium that passes: navigator.webdriver check, plugin/mimeType length checks, window.chrome shape, full bot.sannysoft.com matrix".
The page acts as a "litmus test" for your automation script. When a headless browser (like Chrome in headless mode) visits the page, the site runs a series of JavaScript-based tests to detect:
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 By default, automated browsers set navigator
The website bot.sannysoft.com is a specialized diagnostic tool used by developers to test the "stealthiness" of their web automation scripts. It checks if a browser environment—like those controlled by Puppeteer, Selenium, or Playwright—can be identified as a bot by common anti-bot systems. bot.sannysoft.com Key Features of the Test
Every graphics card renders specific images and WebGL elements slightly differently based on hardware drivers. Sannysoft extracts the WebGL vendor and renderer strings. If these strings explicitly mention terms like "SwiftShader" or "Mesa" (which indicate software-based virtual machine rendering), anti-bot systems know the browser is running inside a headless server environment.
