Lightify – All-in-One Cache & Performance Optimization & Core Web Vitals

Description

Lightify is a lightweight, all-in-one performance helper for WordPress. It bundles a small set of safe, well-understood optimizations you can toggle from a single settings page — no external services, no minified code, and no edits to wp-config.php. Every feature ships off by default, so installing or updating changes nothing until you choose to enable it.

What it does

• Page Cache – Optionally serve a saved copy of pages to logged-out visitors so WordPress can skip rebuilding them on every request. The cache is stored in wp-content/cache/lightify/, is cleared automatically whenever you publish or edit content, and can be cleared manually at any time. Logged-in users, commenters, and requests with query strings are never cached.
• Core Web Vitals monitoring – Optionally measure real-visitor LCP, CLS, INP, FCP, and TTFB directly in the browser using the standard PerformanceObserver API, and view the 75th-percentile results and rating breakdown on the settings page. Measurements are stored on your own site only.
• Bloat Removal – Optionally disable emojis, dashicons (front end), block editor CSS, jQuery Migrate, oEmbed discovery, XML-RPC, and RSS feeds.
• Network Improvements – Add preconnect and dns-prefetch resource hints for the origins you specify, printed by WordPress in the document head.
• Media – Add native loading="lazy" to iframes in your post content.

Every optimization is off or on by a simple checkbox and applies only where noted. If something looks off, just turn the relevant option back off.

External services

This plugin does not connect to, or transmit any data to, any external service. The page cache and Core Web Vitals monitoring both run entirely on your own WordPress installation; vitals data is stored only in your site’s database.

Source Code

Lightify contains no minified, compiled, or obfuscated code. All PHP, CSS, JavaScript, and other source files shipped in the plugin are the original human-readable source and require no build step. The admin stylesheet (assets/css/admin.css) and the Core Web Vitals collector (assets/js/vitals.js) are enqueued directly in their readable form.
