Script Surgery gives you a visual, actionable view of every script and style loaded on your WordPress site — broken down by page type (homepage, single post, product, cart, etc.).
<h4>What it does</h4>
Visual asset inventory 
See every enqueued script and style on each page type: the handle, which plugin or theme added it, file size, whether it loads in <code><head></code> (render-blocking) or footer, and async/defer status.
Source attribution 
Each asset is attributed to: WordPress Core, a plugin (by name), your theme, or an external CDN. No guesswork.
Per-page-type disable rules 
Disable any script or style on specific page types with one click. Elementor scripts loading on your checkout page? Slider scripts loading on cart? Disable them — no code required.
Render-blocking detection 
Scripts loading in <code><head></code> without async or defer are flagged as render-blocking. Styles are flagged similarly. Fix the highest-impact issues first.
Bulk actions 
“Only on this page” — disable a script everywhere except the current page type in one click. Reset individual or all rules at once.
<h4>How data is collected</h4>
Data is captured automatically when a logged-in administrator visits any frontend page. No cron jobs, no external requests. The WordPress admin bar shows a ⚗ indicator on each page type so you know what’s been captured.
<h4>Privacy</h4>
Script Surgery only runs for logged-in administrators. No data is sent externally. All data is stored in your own database (transients + one options entry).

Optimization of included JavaScript- and CSS-files can be a very important thing, if you want a faster site. Many WordPress plugins comes with multiple third-party and/or own JavaScript-files that are then often be included on every page of your site. In worst cases you have more than one of the same file included on your site. That slows down your site!
But also “Render blocking” can easily slow down a website. Every external JavaScript- or CSS-file, that is included in the head of your site, blocks the site from rendering, until all files are completely processed. It’s a common practice to move all these Scripts and Styles (except critical CSS) to the footer of your site, so the rendering is no longer blocked and your website loads faster.
This is where WP Script Optimizer helps you! It makes it possible to control the output of every registered JavaScript or CSS-file. You can easily create rules for it or deactivate files completely. You can also move files to the footer of your site or vice versa.
