OpenSafe is a Chrome extension designed to alert users when they are about to visit a potentially malicious website, particularly those that mimic legitimate URLs to deceive users. By detecting subtle variations in URLs, such as the use of different characters that resemble common ones, OpenSafe aims to prevent users from falling victim to phishing scams and other cyber threats.

This extension serves as a valuable tool in enhancing online security by providing real-time notifications to users, helping them make informed decisions while browsing the web. OpenSafe's proactive approach to identifying deceptive URLs adds an extra layer of protection for Chrome users, contributing to a safer online experience.
