The Kurt Plugin is a minimalistic WordPress plugin designed to internally crawl a website, generate a JSON file containing links present in each page, post, CPT, or sitemap, along with the URLs where each link was found. It also checks if each URL is available, adding a ✅ true or ❌ false value to indicate its availability.

• 🕵️ Crawls all posts, pages, and custom post types.
• 🗂️ Checks the robots.txt file for sitemaps.
• 🔍 Crawls hypothetical sitemap URLs if they exist.
• 🚫 Ignores irrelevant links such as mailto:, javascript:, tel:, whatsapp:, and Google Maps links.
• 📊 Outputs a JSON file with the links found, where they were discovered, and their availability.

1. Upload the plugin to the wp-content/plugins directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.

To generate the JSON file with the links, access your site with the URL parameter ?generate_links_json, e.g., https://yoursite.com/?generate_links_json.

The generated JSON file will have the following structure:

{
    "https://example.com/somepage": {
        "found_in": [
            "https://example.com/otherexample",
            "https://example.com/someotherexample",
            "https://example.com/sitemap.xml"
        ],
        "available": true
    },
    ...
}

• https://example.com/somepage: The URL of the link.
• found_in: An array of URLs where the link was discovered.
• available: A boolean indicating whether the link is available.
