Find broken links, dead in-page anchors and redirect chains on any page — or crawl a whole site. Local, offline, no account. Break the Chain finds the links on a page that quietly stopped working. > > Click the toolbar icon and it checks every link on the page you are looking at, then colours each one: green for fine, blue for a redirect, amber for needs-a-look, red for broken. A floating panel lists the failures, and clicking one jumps straight to it on the page. > > WHAT IT FINDS > • Broken links — 404s, server errors, hosts that no longer resolve > • Dead in-page anchors — a "Jump to pricing" link with no pricing section left to jump to > • Redirect chains — every hop and its status code, including redirect loops > • Broken images, and optionally scripts and stylesheets > • Empty links — href="" and href="#" left behind by a template > > WHOLE-SITE CRAWL > Point it at a site and it walks the pages for you, following your sitemap and respecting robots.txt, with limits you control for how deep and how many pages. > > BUILT TO AVOID FALSE ALARMS > A link checker that cries wolf is worse than none. Sites that refuse automated requests are reported as warnings with an explanation, not as failures. When a server asks it to slow down, it slows down instead of hammering the site. Heading permalinks on GitHub and other documentation sites are understood rather than flagged. > > YOUR DATA STAYS WITH YOU > Everything runs in your browser. No account, no sign-in, no server, no analytics, nothing uploaded anywhere. It works offline apart from the links it is checking. > > Results export to CSV and JSON. Free and open source (MIT)
