🚀 Upgrade to Lightify Pro
The free version already caches your pages, minifies your assets and cleans up WordPress. Lightify Pro removes the limits and adds the heavy-duty optimizations that move Core Web Vitals the most:
Critical CSS & Remove Unused CSS – Inline above-the-fold styles and strip the selectors a page never uses, so nothing render-blocking is left.
Delay JavaScript – Hold non-essential scripts until the first user interaction to cut Total Blocking Time.
Self-Host External Assets – Serve third-party CSS, JS and fonts from your own domain and drop the extra connections.
Advanced Media Optimization – Lightweight YouTube preview placeholders, precise image sizing and critical image preloading.
Speculative Loading – Browser-level prerendering and prefetching for near-instant navigations.
Scheduled Database Cleanup – Automatic pruning of revisions, auto-drafts, spam, orphaned meta and expired transients.
Core Web Vitals Action Items – Prioritised, site-specific fixes instead of a generic score.
Every Advanced Setting – All exclusion rules, cache variants and fine-grained controls unlocked.
Priority Support – Direct help from the team instead of the public support forum.
Simple Pricing – Pro is $29.99 for Lightify on its own, or become a DaftPlug Pro member and get every one of our All-in-One Pro plugins in a single membership at daftplug.com/pricing.
