How It Works

Install our browser plugin from the Chrome Web Store, Firefox Add-ons, or Microsoft Edge Add-ons.

Enter the URL of the website you want to scan in the form above.

Click "Scan for Broken Links" - you'll be redirected to activate the plugin scan.

The plugin will scan your website and display results directly in your browser.

Advanced Scanning Options

For advanced users, you can customize the scan behavior by adding query parameters to the plugin-scan URL.

URL Format

To trigger a scan with all three options configured (max depth, pages only, and verbose debug), navigate to or enter the following URL in your browser (replace {TARGET_URL} with the actual website you want to scan):


                    https://devkit.free/plugin-scan/?target={TARGET_URL}&maxdepth=2&pagesonly=false&debug=verbose

Explanation of the Options

maxdepth=2: Sets the maximum scan depth to 2 (scans the target page plus up to 1 level of internal links; adjust the number as needed, e.g., 1-10).
pagesonly=false: Disables "pages only" mode, so it will also scan images, CSS, and JavaScript files (set to true if you only want page links).
debug=verbose: Enables detailed debug logging for troubleshooting (visible on the page and in the console).

Example with a Real Target

This will start a comprehensive scan of https://example.com with recursive depth, asset scanning, and verbose logging. The scan runs via the browser extension in the background.


                        https://devkit.free/plugin-scan/?target=https://example.com&maxdepth=2&pagesonly=false&debug=verbose
