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.

Example hooks: 
do_action(‘fastpixel/purge/all’); – Purges the entire site cache. 
do_action(‘fastpixel/purge/single’, [‘id’ => 123]); – Purges the cache for a single post, page, or taxonomy term. 
do_action(‘fastpixel/purge/url’, ‘https://example.com/my-landing-page/’); – Purges the cache for a specific URL.
