A Phishing URL Detector is a security tool that analyzes URLs to identify potential phishing attempts. Phishing URLs are designed to trick users into visiting fake websites that look legitimate — often mimicking banks, social media platforms, email services, or payment processors — to steal sensitive information like passwords, credit card numbers, or personal data.
This tool examines URLs for common phishing indicators including:
No. All analysis is performed locally in your browser using JavaScript. The URL you enter never leaves your device. No data is sent to any external server.
No tool can provide 100% guarantee. This detector checks for known phishing patterns and red flags, but sophisticated phishing sites may evade automated detection. Always use your best judgment and check for other signs like poor grammar, urgent language, and unexpected requests for personal information.
If you identify a phishing URL, do not visit it. Report it to the relevant organization being impersonated, and to anti-phishing services like Google Safe Browsing, PhishTank, or the APWG (Anti-Phishing Working Group).
The risk score (0-100) is calculated based on the number and severity of phishing indicators found. Each indicator has a weighted score — critical indicators like suspicious TLDs and lookalike domains add more weight, while minor indicators like missing HTTPS have less impact. The final score helps you quickly assess the overall risk level.
