And so, on the testing floor of Sannysoft Industries, amid the cold hum of machines and the rigid grid of white tiles, a small line of green text appeared every morning at 9:01 AM:
For businesses that rely on web scraping for market intelligence, price monitoring, or lead generation, being blocked directly impacts revenue. A stealthy browser that passes the SannySoft test can quietly extract data for months. A detectable browser, however, is often blocked within hours, leading to data gaps and the need for expensive proxy infrastructure.
Test Name, Result. User Agent (Old). WebDriver (New), present (failed). WebDriver Advanced, failed. Chrome (New), missing (failed) bot.sannysoft.com bot.sannysoft
While some contemporary developers consider the site slightly dated compared to commercial enterprise-grade platforms, it remains highly popular for diagnosing core automation leaks before deploying code against advanced firewalls. Core Detection Mechanisms Evaluated by SannySoft
Forging a Chrome User-Agent while executing on a non-Chrome architecture. 2. WebDriver Detection What it checks: Looks for the navigator.webdriver property. And so, on the testing floor of Sannysoft
: Real Chrome browsers possess a native window.chrome object containing specific runtime and webstore attributes. Headless automation environments often omit this object entirely, causing a mismatch that Sannysoft highlights.
The core of the plugin lies in the stealth.min.js file, which can be generated using the command npx extract-stealth-evasions . You can then load this script into your automation script to apply the patches before any page loads: Test Name, Result
is a popular, free online testing tool used by developers and security researchers to check for "browser leaks" that reveal whether a web browser is being controlled by automated software (a bot) rather than a human user. 🔍 Purpose & Function
// add stealth plugin and use defaults (all evasion techniques) const StealthPlugin = require('puppeteer-extra-plugin-stealth'); puppeteer.use(StealthPlugin());
From that day on, Bot.sannysoft was no longer a tool. It was a partner . Developers began leaving comments in code like: // Sanny, ignore this mess, I’ll refactor tomorrow. And Bot.sannysoft would mark those sections as DEFERRED - Trust noted.
SannySoft's Antibot test is a single-page web utility that runs a battery of client-side JavaScript checks. It analyzes the environment of the visiting browser to detect common discrepancies exposed by automation frameworks.
