Browser Detection

Headless Browser

Detect Selenium, Puppeteer, and Playwright automation

What it detects

Identifies browsers running in headless mode or controlled by automation frameworks. Checks for telltale markers left by Selenium, Puppeteer, Playwright, and other browser automation tools.

How it works

Inspects dozens of browser properties for automation markers: navigator.webdriver flag, Chrome DevTools protocol indicators, missing browser plugins, inconsistent window dimensions, and framework-specific global variables.
