How to Use:

1. Open the webpage you want to check.
2. Click the Dead Link Detector icon in the Chrome toolbar.
3. Click Scan.
4. Review the summary counts in the popup.
5. Check highlighted links directly on the page.
6. Open the full table report for filtering, searching, rechecking, copying, printing, or exporting results.

Scan Range:

You can limit a scan to a specific part of the page using a CSS selector, such as main, #content, or .article-body. This is useful when you only want to check links inside an article, product page, footer, or specific content section.


Privacy Friendly:

Dead Link Detector runs locally in your browser. Based on the current extension files, it does not send scanned URLs, page content, or report data to the developer’s server.

When a scan is started, the extension checks the links found on the page by making direct browser requests to those link URLs to determine their status. Settings and preferences are saved locally using Chrome storage.


Disclaimer:

Dead Link Detector provides status checks based on browser-accessible HTTP responses. Some links may show as warnings if a website blocks automated checks, requires login, blocks cross-origin requests, rate limits requests, or behaves differently for HEAD/GET requests.
