Universal CAPTCHA Detector

About

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.
