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 -- optional 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

Installation

composer require justinholtweb/craft-appleseed
php craft plugin/install appleseed

Console Commands

# Run a full scan
php craft appleseed/scan

# Scan a single entry
php craft appleseed/scan/entry --id=123

# Check a single URL
php craft appleseed/check-url https://example.com

Configuration

Visit Settings > Appleseed in the control panel, or create a config/appleseed.php file:

<?php

return [
    'checkExternalLinks' => true,
    'timeout' => 10,
    'maxRetries' => 3,
    'rateLimitPerSecond' => 1.0,
    'spiderEnabled' => true,
    'maxPagesToSpider' => 200,
    'scanBatchSize' => 50,
    'scanFrequency' => 'manual', // manual, daily, weekly, monthly
    'scanOnEntrySave' => false,
    'notificationEmails' => '',
    'notificationThreshold' => 1,
    'emailLayoutTemplate' => '',
    'ignorePatterns' => '',
    'userAgent' => 'Appleseed Link Checker (Craft CMS)',
    // Status the dashboard filters by on first load: '' (all), broken, redirect,
    // working, server_error, timeout, dns_error
    'defaultStatusFilter' => '',
];

Scheduled scans

Scans are manual by default -- nothing is queued when the plugin is installed or updated. Pick a scanFrequency of daily, weekly, or monthly to scan automatically. The schedule is measured from your most recent completed scan, so run one from the dashboard (or with php craft appleseed/scan) to start the clock.

Read-only settings

When allowAdminChanges is disabled for the environment, the settings screen renders read-only: the fields show the active configuration but can't be edited, and saving is rejected. Set your values in config/appleseed.php on those environments.
