Broken Link Checker – Find Broken Links

Broken Link Checker helps you quickly scan the current webpage and identify broken links, 404 errors, redirects, working URLs and unreachable links.

Instead of checking every link manually, start a scan and let the extension inspect links on the current page automatically. Results are organized by status so you can quickly find problematic URLs and review working or redirected links.

Find Broken Links on Any Webpage

Use Broken Link Checker to scan the links available on the current webpage and quickly identify URLs that may no longer work.

The extension checks each discovered link and organizes the results into clear categories:

• Working
• Redirects
• Broken
• Unknown

This makes it easier to review website links without opening every URL manually.

Detect 404 Errors and Broken URLs

Broken pages can create a poor user experience and make website maintenance more difficult.

The built-in broken URL checker helps identify HTTP errors and other failed responses, making it useful for checking webpages, blog posts, landing pages and other sites containing multiple links.

Website Broken Link Checker

Start a scan directly from the webpage you are viewing.

The extension collects unique HTTP and HTTPS links from the current page and checks their status in the background.

You can see:

• Total links
• Working links
• Redirects
• Broken links
• Unknown links

Filter Scan Results

Quickly focus on the links that matter.

Use the result filters to display:

• All Links
• Broken Links
• Redirects
• Working Links

Each result includes its status, URL and response time.

Background Link Scanning

Link scans run as background jobs.

After the URL list has been collected, closing the extension popup does not automatically remove the active scan. Reopen the extension to view the latest progress and available results.

You can also cancel an active scan while keeping the links that have already been checked.

Save Reports by Domain

Completed scans can be saved locally and organized by website domain.

This allows you to build a local library of previous broken link reports and return to them later without mixing reports from different websites.

Export Broken Link Reports

Export scan results to CSV for further review or website maintenance.

You can export:

• Current scan results
• Reports from one saved domain
• Reports from multiple selected domains
• All selected reports as one combined CSV

Exported reports can include link status, category, URL, final URL and response time.

Local & Private

Broken Link Checker stores saved reports locally in your browser.

Scan history is not sent to an external analytics or report-storage service.

Useful for

• Website owners
• SEO professionals
• Developers
• Bloggers
• Content managers
• QA testers
• Website maintenance
• Link auditing

Whether you need a broken link checker, website broken link checker, broken URL checker, broken link finder or 404 broken link checker, this extension provides a simple way to scan links and identify problematic URLs directly from your browser.
