Broken Link Checker – 404 & Dead Link Finder

Scan the page or site in your tab for broken links, dead links and 404s. Results stream in live.

Find every broken link on the page you are looking at, in seconds. Click the extension icon and Broken Link Checker scans the current page for dead links, 404s, soft 404s, redirect chains, server errors and SSL problems. The scan runs on our servers, not in your browser, so nothing slows down and nothing is installed on the site you are checking. Results stream in live as they are found. Each result shows the status code, the URL and the anchor text, and you can open the link, copy it, or highlight it on the page. Open the side panel to keep the list in view while you fix things. WHAT IT CHECKS - 404 and 410 dead links - Soft 404s, where a page returns 200 but has no real content - Server errors in the 5xx range - Redirect chains and loops - Broken images - Links blocked by SSL or certificate errors - Internal and external links, with external checking optional WHO IT IS FOR SEO specialists auditing a client site before a report. Developers checking a page after a migration. Store owners who need to know that product links still resolve. Anyone who has published a page and wants to know it is clean before someone else finds out it is not. FREE AND PAID The free plan gives you 50 page scans a month, with no card required. Paid plans add more scans, scheduled re-scans, email alerts and site wide crawls. BEYOND THE EXTENSION Your account at brokenlinkchecker.io also gives you keyword rank tracking, Bing rank tracking, AI visibility monitoring, an internal link optimizer, an SEO and AEO audit, and uptime monitoring. Those tools run on the web, and the extension links to them. The same link checker is also available as a WordPress plugin and a Shopify app. Made by Norse Digital Group LLC.
