PlugoSpeed is a WordPress performance plugin that combines page caching, asset optimization, and Core Web Vitals improvements in a single lightweight package.
It generates static HTML cache files served directly from disk via Apache — bypassing PHP and WordPress on cached requests. In testing on a standard VPS, this approach achieves sub-50ms TTFB and PageSpeed scores of 95/100 on desktop.
A React 18 dashboard provides real-time cache hit rates, bandwidth saved, and PageSpeed score tracking — no jQuery required.
<h4>Core Features (Free)</h4>
Static HTML Cache 
Pages are stored as static <code>.html</code> files on disk. Apache serves them directly — no PHP, no database, no WordPress bootstrap. Cache TTL is configurable (default: 24 hours).
HTML Minification 
Removes unnecessary whitespace and comments from the final HTML output, reducing page size without affecting content or functionality.
CSS Minification 
Minifies stylesheet files inline, reducing transfer size. Combine is intentionally disabled by default for HTTP/2 compatibility.
JavaScript Defer 
Adds <code>defer</code> to non-critical scripts, improving Time to Interactive (TTI) and Largest Contentful Paint (LCP) scores on mobile.
Image Lazy Loading 
Adds native <code>loading="lazy"</code> to images and iframes below the fold. Injects explicit <code>width</code> and <code>height</code> attributes to reduce Cumulative Layout Shift (CLS).
Database Cleanup 
Scheduled cleanup of post revisions, auto-drafts, spam comments, and expired transients. Configurable schedule: daily, weekly, or monthly.
Cache Preloading 
After purge, PlugoSpeed re-warms the cache automatically by walking your XML sitemap. Rate-limited to avoid server overload.
Auto Cache Purge 
Cache is invalidated on post save, theme change, plugin activation, and WooCommerce stock/price updates.
PageSpeed Dashboard 
Tracks your Google PageSpeed Insights score over time with a 30-day graph. Shows live cache hit/miss ratio, bandwidth saved, and page count.
<h4>Pro Features</h4>
Remove Unused CSS (RUCSS) 
Generates a per-page stylesheet containing only the CSS rules that are actually used. Eliminates render-blocking CSS from page builders and plugin stylesheets. Requires a PlugoPress API key.
Critical CSS 
Inlines the above-the-fold CSS directly in <code><head></code>, eliminating render-blocking for a faster LCP. Requires a PlugoPress API key.
WebP Image Serving 
Automatically serves <code>.webp</code> versions of images to supported browsers, reducing image payload by 25–35% without quality loss.

PlugoSpeed

A WordPress cache plugin delivering static HTML cache, page caching, CSS minification, JavaScript defer, lazy load, and Core Web Vitals improvements.

WRD Studio

Core Web Vitals Monitor adds a sidebar to posts & pages and dashboard widget that show you how quickly your pages are loading for real visitors. We report page load times from real users as they experience your site so your data isn’t limited to your internet speed.
<h4>Core Web Vitals</h4>
This plugin uses the Google Chrome team’s <a href="https://github.com/GoogleChrome/web-vitals" rel="nofollow ugc">web vitals package</a> to ensure you get the most accurate data from visitor’s loading experience.
<h4>Measurable Insights</h4>
With real user data, you can see if the changes you’re making are making a measurable impact for users. We collect all the core web vitals that Google uses as ranking factors: 
* Cumulative Layout Shift (CLS) 
* First Input Delay (FID) 
* Largest Contentful Paint (LCP)
Plus the following experimental/less key statistics: 
* First Contentful Paint (FCP) 
* Input to Next Paint (INP) 
* Time to First Byte (TTFB)
<h4>Tiny and Focused</h4>
The Core Web Vitals Monitor is a tiny plugin focused on one thing: accurate page speed data. Our load time tracker script is only 3.2kb large and is loaded asynchronously so it won’t increase your page load times.
<h3>FAQS</h3>
Does this work with the Gutenberg Block Editor?
Yes! The Core Web Vitals Monitor will appear on the right hand side under your post/page’s publishing settings.
Does this work with the Classic Editor?
Yes! The Core Web Vitals Monitor will appear on the right hand side under your post/page’s publishing settings.
Can I see page load times for a specific URL?
Yes, when you open a page or post in your WordPress admin area those statistics are only for the URL of that post. You can scroll down to the bottom of the monitor to see how many visits and what URL the data is for.
Where can I see the page load times for the entire site?
If you visit your WordPress admin dashboard, you’ll see the Core Web Vitals for all URLs collected on your site.
Will URL query parameters mess this up?
No. When we track the URL the user is on we strip back everything except the scheme (http or https), host name (www.example.com) and the path (/about-me). If the user is on a page with query parameters or a hash then this will be removed. The only thing that may lead to inconsistent results is if your scheme is inconsistent, for example if users are able to visit the site through HTTP and HTTPS.
