dislike404.com Broken Link Checker

dislike404.com is a free, cloud-based broken link checker that automatically monitors your website for 404 errors, broken links, and HTTP issues — and sends you email alerts before search engines or visitors notice anything is wrong.

The scanning runs entirely on dislike404.com’s servers, not on your WordPress installation. This plugin gives you a convenient way to trigger on-demand scans and check results directly from your WordPress admin panel — without having to log in to dislike404.com each time.

dislike404.com is completely free. Unverified websites scan up to 200 pages; once you verify your site, the limit rises to 50,000 pages per scan.

What dislike404.com does

• Automatically scans your website on a configurable schedule (daily to monthly)
• Checks internal pages, external links, images, and scripts for HTTP errors
• Validates redirect chains across multiple hops
• Sends email alerts when broken links or errors are detected
• GDPR-compliant — servers hosted in Germany, no third-party trackers

What this plugin adds

• Trigger an on-demand scan with a single click from the WordPress Settings page
• Optional “Scan Now” button in the WordPress admin bar for quick access on every page
• Real-time scan status — see when a scan is running, finished, or if errors were found
• Direct link to the full scan report on dislike404.com
• Verify your website directly from the plugin settings (if WordPress is installed at the root) — manual verification via dislike404.com is always available as an alternative

Requirements

• A free account at dislike404.com
• Your WordPress site added to your dislike404.com account
• An API token generated in your dislike404.com profile
