BrokenBuster

Intelligent broken-link scanner. Privacy-first: all HTTP checks run in your browser.

**The Ultimate Technical SEO Broken Link Checker for the Modern Web** Validate your website's internal link health and find dead links with BrokenBuster. Designed specifically for technical SEO auditing, developer documentation, and staging environments, BrokenBuster is the most reliable, privacy-first dead link scanner for Chromium. Unlike legacy extensions that freeze on massive pages or get blocked by modern bot protections, BrokenBuster handles the modern web safely from your browser—no backend proxies, no hidden data collection, and no false positives. **Standout Features for Technical SEO:** * **Deep Anchor Fragment Validation**: Did you link to `page.html#pricing` but someone deleted the ID on the target page? BrokenBuster parses the target DOM to validate in-page anchor links—a critical SEO capability missing from standard checkers. * **False Positive Bot-Wall Detection**: Built-in semantic fingerprinting for Cloudflare, Akamai, and Imperva. Stop wasting time manually verifying fake 403 HTTP errors when sites block basic crawling bots. * **Privacy-First Local Engine**: Your staging site URLs and sensitive page content are never sent to a cloud backend. Every live check runs locally, making it the perfect bulk URL scanner for private portals. * **Comprehensive Asset Scanning**: Go beyond standard URLs. We validate `<script src>` imports, CSS stylesheets, image assets, and standard `<a>` tags for holistic internal link health audits. * **Advanced Filtering Controls**: Filter out `rel="nofollow"` links, isolate only external links, or globally ignore heavy social media domains with a single click. * **Wayback Machine Restoration**: Instantly find archived snapshots of dead links with an integrated Wayback Machine CDX API lookup. * **Professional HTML & CSV Exports**: Generate interactive, high-contrast standalone HTML reports or raw CSV data for client deliverables. **Who is this for?** * **Technical SEO Specialists**: Conduct deep internal link health audits and detect hidden 404 errors across complex JS-heavy or gated web apps. * **Technical Writers & Content Managers**: Validate thousands of in-page anchor links inside massive documentation hubs and ensure content continuity. * **Web Developers**: A secure, fast bulk URL scanner for QA testing in private staging and pre-flight environments.
