NaveenCodes Core Web Vitals<\/strong> is the most complete free performance plugin for WordPress. It measures Core Web Vitals from your actual visitors, shows you exactly which pages are slow and why, and gives you the tools to fix every issue \u2014 from CSS minification to database cleanup.<\/p>\n\n

Real User Monitoring (RUM):<\/strong>\nUnlike lab tools (Lighthouse, PageSpeed Insights), this plugin measures from your real visitors on real devices and networks \u2014 the same signal Google uses for Search ranking.<\/p>\n\n

Metrics collected from every visitor:<\/strong>\n* LCP<\/strong> (Largest Contentful Paint) \u2014 loading performance\n* CLS<\/strong> (Cumulative Layout Shift) \u2014 visual stability\n* INP<\/strong> (Interaction to Next Paint) \u2014 responsiveness\n* FCP<\/strong> (First Contentful Paint) \u2014 time to first render\n* TTFB<\/strong> (Time to First Byte) \u2014 server response speed<\/p>\n\n

Slow Request Detection:<\/strong>\nThe collector uses the browser's Resource Timing API to identify the slowest network requests on each page \u2014 scripts, stylesheets, images, fonts \u2014 and surfaces them in the Assets page with load time, file size and render-blocking status.<\/p>\n\n

Page Analysis:<\/strong>\n* See every published post and page with its real CWV scores\n* Per-page issues with specific fix suggestions\n* Quick Fix button \u2014 automatically enables the right optimizer settings\n* Per-page overrides \u2014 exclude specific scripts\/styles on individual pages\n* Preload a specific URL (hero image, font) for a page<\/p>\n\n

Built-in Speed Optimizer \u2014 13 one-click fixes:<\/strong><\/p>\n\n

Images:<\/em>\n* Lazy Load Images (LCP)<\/p>\n\n

Resources:<\/em>\n* Preconnect hints for Google Fonts (FCP)\n* Defer non-critical JavaScript (LCP)\n* Remove version query strings<\/p>\n\n

WordPress Cleanup:<\/em>\n* Remove emoji scripts (-33 KB)\n* Disable Dashicons for guests (-30 KB)\n* Disable self-pingbacks<\/p>\n\n

Minification:<\/em>\n* Minify CSS files \u2014 local files with cache\n* Minify JavaScript files \u2014 local files with cache\n* Minify HTML output<\/p>\n\n

Advanced Resources:<\/em>\n* Google Fonts \u2014 non-blocking async load (FCP)\n* DNS prefetch for external domains (TTFB)\n* Preload theme stylesheet (FCP)<\/p>\n\n

Database Optimizer:<\/strong>\n* Clean post revisions\n* Remove spam comments\n* Delete trashed posts and comments\n* Remove expired transients\n* Delete auto-draft posts\n* Remove orphaned post meta\n* OPTIMIZE TABLE \u2014 defragment and reclaim disk space\n* Visual table size breakdown<\/p>\n\n

Dashboard:<\/strong>\n* Per-metric traffic-light status (Good \/ Needs Work \/ Poor)\n* 7-day trend sparklines\n* Slowest pages table\n* Device filter (mobile \/ tablet \/ desktop)<\/p>\n\n

Privacy & Architecture:<\/strong>\n* No external service \u2014 all data in your WordPress database\n* Configurable sampling rate (1\u2013100%)\n* Configurable data retention (7\u2013365 days)\n* Exclude specific URLs or logged-in users\n* Automatic daily cleanup cron<\/p>\n\n

This plugin is 100% free \u2014 no premium tier, no ads, no upsells. Made with love by MAA Labs in memory of Maa \u2764\ufe0f<\/p>\n\n\n

    \n
  1. Upload the plugin folder to \/wp-content\/plugins\/<\/code> or install via Plugins \u2192 Add New<\/strong>.<\/li>\n
  2. Activate the plugin.<\/li>\n
  3. Go to Core Web Vitals \u2192 Dashboard<\/strong>.<\/li>\n
  4. Visit a few pages \u2014 data appears within minutes.<\/li>\n
  5. Enable optimizations under Core Web Vitals \u2192 Optimizer<\/strong>.<\/li>\n
  6. Check Core Web Vitals \u2192 Page Analysis<\/strong> for per-page issues.<\/li>\n
  7. Use Core Web Vitals \u2192 Database<\/strong> to clean up your database.<\/li>\n<\/ol>\n\n\n
    \n

    How long until I see data?<\/h3><\/dt>\n

    Data appears within minutes of activation. Visit a few pages on your site, then check the Dashboard.<\/p><\/dd>\n

    Does this affect page load speed?<\/h3><\/dt>\n

    The collector script is tiny (~3 KB), non-blocking, and sends data on page unload using navigator.sendBeacon<\/code>. Zero impact on your Core Web Vitals scores.<\/p><\/dd>\n

    How does CSS\/JS minification work?<\/h3><\/dt>\n

    Local CSS and JS files are read, minified using a pure-PHP minifier, and cached in uploads\/ncwv-min\/<\/code>. The cached version is served instead of the original. Clear the cache from the Assets page after updating your theme.<\/p><\/dd>\n

    Is data sent to an external server?<\/h3><\/dt>\n

    No. All data is stored locally in your WordPress database.<\/p><\/dd>\n

    What does the Database Optimizer do?<\/h3><\/dt>\n

    It finds and removes post revisions, spam comments, trashed items, expired transients, auto-draft posts and orphaned post meta. It also runs OPTIMIZE TABLE<\/code> to reclaim disk space.<\/p><\/dd>\n

    Can I exclude certain pages or scripts?<\/h3><\/dt>\n

    Yes \u2014 use Page Analysis \u2192 Settings<\/strong> to exclude specific script\/style handles on individual pages. Use Settings \u2192 Exclude URLs<\/strong> to skip pages from CWV collection.<\/p><\/dd>\n\n<\/dl>\n\n\n
