Appleseed - Broken Link Checker for Craft CMS 5

Appleseed proactively discovers and checks every link across your Craft CMS site, helping you find and fix broken links before your visitors do.

Features

• Hybrid link discovery -- scans entry fields in the database and spiders rendered pages
• Smart HTTP checking -- HEAD-first with GET fallback, retries with exponential backoff, per-domain rate limiting
• CP Dashboard -- summary cards, filterable results table, detail views, ignore/rescan actions
• Scheduled scans -- daily, weekly, or monthly automatic scanning
• Entry-save scanning -- optionally check links whenever an entry is saved
• Email notifications -- get notified when broken links exceed your threshold
• CSV export -- download results for offline review
• Ignore patterns -- regex-based URL exclusion
• Console commands -- craft appleseed/scan for CLI/cron usage
• Badge count -- broken link count shown in the CP nav

Requirements

• Craft CMS 5.0.0 or later
• PHP 8.2 or later
