# Dead Link Crawler

> Dead Link Crawler is a SaaS web app that crawls websites and identifies broken links (404s, timeouts, DNS failures, SSL errors, and more). It is built for web developers, SEO professionals, and site owners who want to maintain link health across their properties.

Dead Link Crawler performs server-side crawls using a breadth-first algorithm with no CORS issues and no browser required. It streams results in real time, saves scan history for authenticated users, and supports exporting reports to Google Docs.
