How to make python selenium less detectable? - Stack Overflow
When a browser visits the Sannysoft tool, the site runs an array of client-side JavaScript tests to look for telltale signs of automated environments. The core checks fall into several distinct categories: 1. The WebDriver Flag
with a specific automation tool like Python Selenium or Node.js Playwright?
For Selenium users, the selenium-stealth library is highly effective. It automatically hides the WebDriver flag, sets realistic plugins, and manages languages. bot.sannysoft
Standard out-of-the-box automation frameworks are not designed to be stealthy. They are designed for automated testing. As a result, they broadcast clear signals that declare, "I am a bot."
The tests target many signals that can give away automated browsers. Among the most critical signals, navigator.webdriver is a primary giveaway—a true value in headless browsers is the most common bot signal. Automated browsers also often have empty or abnormal plugin lists ( navigator.plugins ) and frequently use software-based WebGL renderers like SwiftShader, which are major red flags. The test also checks basic window dimensions and inconsistencies between the user-agent platform and the reported navigator.platform . This comprehensive testing makes the platform an essential resource for developers serious about web automation.
The senior architect, reviewing logs the next morning, nearly choked on his bagel. “Did the bot just suggest a nap for a dev?” How to make python selenium less detectable

Checking if navigator.webdriver is set to true. The WebDriver Flag with a specific automation tool
For developers building automated scripts, has emerged as an essential, industry-standard benchmark tool. It allows you to test exactly how "human" your automated browser looks to the outside world. What is Bot.Sannysoft?
When running Google Chrome in --headless mode to save server resources, the browser naturally drops or alters specific features. Sannysoft checks for these telltale headless signatures:
By default, standard automation tools set the navigator.webdriver JavaScript flag to true . Human-operated browsers have this set to false or undefined . Anti-bot systems check this property instantly; if it is active, the bot is caught immediately. 2. Chrome Inconsistencies ( window.chrome )
If you build web crawlers using tools like Selenium, Puppeteer, or Playwright, bypassing modern Web Application Firewalls (WAFs) like Cloudflare, DataDome, or Akamai requires absolute invisibility. The serves as your ultimate training ground. Understanding the Sannysoft Test Suite
