Universal CAPTCHA Detector

Syed Idrees

Universal CAPTCHA Detector is a lightweight Chrome extension that automatically detects the presence of CAPTCHA challenges on websites you visit — including Google reCAPTCHA, hCaptcha, Cloudflare Turnstile, and even custom CAPTCHA implementations. 🔍 Key Features: ✅ Detects reCAPTCHA v2 and v3 ✅ Detects hCaptcha and Cloudflare Turnstile ✅ Heuristically detects traditional CAPTCHA images or text prompts ✅ Runs silently and efficiently on every page ✅ Notifies you via a subtle icon badge when CAPTCHA is found ✅ No popups, no interruptions — just simple visual alerts ✅ Works automatically, no setup required 🧠 How It Works: This extension scans the page's content for common CAPTCHA providers and visual patterns. When a CAPTCHA is detected, you'll see a red "!" badge on the extension icon. It works across all websites and handles dynamically loaded CAPTCHAs using smart DOM monitoring. 🔒 Privacy First: This extension does not collect or transmit any user data. Detection happens entirely on your browser. We do not use analytics, third-party scripts, or any tracking technologies.
