Broken Link Highlighter

Broken Link Highlighter is a powerful Chrome extension designed to revolutionize how web developers, content managers, and SEO professionals audit website links. With its cutting-edge concurrent scanning technology, this extension can check up to 12 links simultaneously, dramatically reducing the time needed to identify broken links across entire webpages. The intelligent auto-detection system automatically identifies page sections including headers, main content, footers, and sidebars using semantic HTML5 elements, ensuring comprehensive coverage without manual configuration. The sleek dark interface features a compact 280px popup that provides real-time progress tracking with percentage completion and current URL display, allowing you to monitor scanning progress at a glance. Customizable exclusion filters let you skip specific areas like admin panels or comment sections, while persistent settings ensure your preferences are saved across sessions. Beyond simple link checking, the extension provides detailed statistics with color-coded results—green for working links, red for broken ones, orange for redirects, and gray for errors—making it easy to quickly assess page health and prioritize fixes. Built with performance and privacy in mind, all processing happens locally in your browser with no data sent to external servers, while the optimized HEAD request method and 8-second timeout ensure fast, reliable scanning even on large, complex websites.
