About this plugin
Dr. Speed: AI Assets Scanner debloats WordPress by automatically finding unused CSS and JavaScript on individual pages. It scans desktop and mobile pages, VERIFIES asset-unloading candidates, and prepares per-page rules to dequeue unnecessary files.
Unload files where they aren’t needed to speed up pages and reduce HTTP requests, page weight, bandwidth, and browser work. Fewer scripts and stylesheets per page means better performance and page speed. Review the results before applying rules.
Unload unused CSS and JavaScript to optimize page speed
Most WordPress sites load every plugin’s CSS and JavaScript on every page: a contact-form script on the blog, a slider stylesheet on checkout, a page-builder bundle on a plain post. AI Assets Scanner is an AI-assisted asset manager for exactly that problem. It finds the unused CSS and unused JavaScript files on each page, checks that removing them is safe, and gives you per-page dequeue rules.
Applied with Code Unloader, those rules unload the files on the pages that do not need them, which is the fastest way to debloat a site and optimize CSS and JavaScript loading without touching your theme, your plugins, or the files themselves.

AI Assets Scanner generates the rules; Code Unloader applies them. Install Code Unloader on the scanned site for one-click Push/Sync or manual JSON import.
Use Sync to add recommendations while keeping your existing rules. Push replaces the active setup after taking a snapshot. You can undo the last Push/Sync.
What the scanner does
- Unload unused CSS and JS per page: the rules dequeue whole files where a page does not need them. Nothing is minified, rewritten, or deleted.
- Automatic discovery: choose pages, posts, and custom post types from your sitemap or database.
- Desktop and mobile scans: inspect page assets in a real browser and review page-level recommendations.
- Safe and Aggressive groups: separate assets not loaded on a page from loaded assets that passed removal checks.
- Protected assets: safeguards retain detected payment, form, anti-spam, analytics, and WordPress core assets and report what was kept.
- Optimizer awareness: detect supported tools such as WP Rocket, FlyingPress, LiteSpeed Cache, Autoptimize and Perfmatters, and report scan bypass status.
- History and exports: review credit usage, re-download JSON rules, and export scan history to ZIP.
- Access guidance: configure Cloudflare/firewall access or HTTP Basic Auth for protected staging pages.
