Sannysoft emerged as a critical tool for developers to test if their "stealth" bots were actually as invisible as they thought. The site runs a series of sophisticated tests to see if a browser is lying about its identity.
const puppeteer = require('puppeteer');
In the fragmented world of headless browsers, virtual frame buffers, and CI runners, bot.sannysoft serves as the for automation health. Whether you are a solo developer trying to debug a Docker container or a large enterprise maintaining a Selenium Grid with 100+ nodes, this simple page saves hours of guesswork.
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
By default, automated browsers set navigator.webdriver to true . Sannysoft checks this property immediately; if it isn't "missing" or "false," you are instantly identified as a bot. bot.sannysoft
: A specific test for the presence of a "hairline" (fractional pixel rendering), which is often missing or incorrectly handled in headless browser environments.
Bot.sannysoft generated a second, unprecedented report: SUPPLEMENTAL - Developer fatigue likely contributor. Recommend 8 hours of rest for Mark V. before patch.
: Using tools like AdsPower or GoLogin, which are designed specifically to pass fingerprinting tests by creating unique, isolated browser profiles.
Headless browsers often inadvertently identify themselves through their user agent string. For example, a headless Chrome may contain the substring "HeadlessChrome" right in its identity. If bot.sannysoft.com detects this, it will flag the test as a failure, indicating that even a simple header check can identify your script. Sannysoft emerged as a critical tool for developers
Bot.sannysoft is a single software product but rather a reference domain ( bot.sannysoft.com ) or a namespace used in tutorials, demo projects, and automation examples — particularly for headless browser detection evasion and automation testing .
If you pass fully, your bot looks very human-like to basic detection scripts.

// puppeteer-extra is a drop-in replacement for puppeteer, // it augments the installed puppeteer with plugin functionality const puppeteer = require('puppeteer-extra');
These modern frameworks offer better stealth capabilities, but they are not invisible by default. One GitHub issue discussing apify/fingerprint-suite bluntly states: "The headless mode from launchPlaywright doesn't not pass tests on https://bot.sannysoft.com/". Running these frameworks in their default configuration will almost certainly result in red flags on the detection matrix.
Enter bot.sannysoft.com . While not a piece of software itself, refers to a legendary resource in the automation community: The Selenium Grid / WebDriver Testing Page hosted by SannySoft . This page (often navigated to via bot.sannysoft.com ) serves as the gold-standard benchmark for verifying that your headless or UI-based browser automation setup is working correctly.
