Broken Link Detector is a fast, privacy-first Chrome extension that instantly audits any webpage for link health. Designed for web professionals who are tired of clunky SEO tools, it runs completely locally in your browser and lives in a persistent sidebar—meaning no annoying popups that close every time you click the page. It evaluates every link in real-time with an intuitive color-coded system (Green for working, Yellow for redirects, Red for broken). The tool goes beyond basic 404 detection by accurately identifying server errors (500s), connection timeouts, and 301/302 redirects (displaying their final destination). It also features a brilliant "Focus Mode" that visually highlights the broken link directly on the webpage so you can find and fix it instantly. Key Features Real-Time Scanning: Watch results populate instantly with a live progress bar. Persistent Sidebar: The tool docks to the side of your screen and stays open while you work. Comprehensive Detection: Finds 404s, server errors (500, 502, 503), timeouts, and 301/302 redirects. Focus Mode: Click any link in the report to visually highlight it directly on the webpage. 100% Local & Private: No account required. All scanning happens in the browser, meaning your data never touches a remote server. CSV Export: Download your full audit report in one click.
