What It Detects

The bookmarklet scans for WordPress plugins using multiple detection methods:

• Script and Link Tags: Scans <script> and <link> elements for /wp-content/plugins/ paths
• Meta Tags: Checks <meta name="generator"> tags for plugin signatures (Yoast SEO, Elementor, WooCommerce, etc.)
• HTML Comments: Searches for plugin-related comments left by caching and optimization plugins

Detection Results

• Plugins Found: Displays an alphabetically sorted list of detected plugin names
• No Plugins Detected: The site is WordPress but has no publicly detectable plugins
• Not a WordPress Site: No WordPress indicators found (wp-content, wp-includes, or WordPress generator meta)

Browser Compatibility

Works in all modern browsers:

• Chrome
• Firefox
• Safari
• Edge
• Opera

The bookmarklet uses standard JavaScript APIs and requires no external dependencies.

Building from Source

npm install
npm run build

This generates:

• dist/bookmarklet.txt - The bookmarklet code for manual installation
• dist/test.html - A test page with the draggable bookmarklet link
