Site Scripts & Speed Manager for WordPress

Site Scripts & Speed Manager gives you full visibility and control over every JavaScript file loading on your WordPress site.

Most performance plugins offer a blanket “defer all scripts” checkbox — then you spend hours figuring out what broke. This plugin takes a different approach: see first, then optimize.

Crawl your entire site or scan a single page to discover every script

See exactly what each script is, where it comes from, how it currently loads, and which pages it appears on

Choose per-script: Defer, Async, or None — with visual badges, filter tabs, and live search

Master kill switch — if anything breaks, flip it off instantly. No cache clearing needed.

Full Site Crawl Don’t just scan one page — crawl your entire site with a single click. The plugin automatically discovers your pages, posts, and category archives (up to 50 pages, 10 posts, and 5 categories), scans each one for scripts, and merges the results into a unified view. An animated progress bar shows crawl status in real-time.

Per-Page Script Tracking After a full site crawl, every script shows how many pages it appears on. Hover over the count to see the list of page paths. Scripts that only load on inner pages (not the homepage) are highlighted with an “inner only” badge, so you can immediately spot page-specific scripts from plugins like WooCommerce, contact forms, or page builders.

Per-Script Loading Control Each discovered script gets its own dropdown: Defer, Async, or None. No blanket rules — you choose exactly how each script loads based on what it is and what it does. Color-coded dropdowns make it easy to see your choices at a glance: blue for Defer, amber for Async.

Protected Scripts jQuery Core and jQuery Migrate are automatically locked and cannot be deferred or async’d. Deferring jQuery breaks the majority of WordPress sites, so the plugin prevents you from making that mistake. Protected scripts show a lock icon and their dropdowns are disabled.
