Lightify creates gzipped HTML snapshots of your pages and serves them directly via an advanced-cache.php drop-in, bypassing most of WordPress’s PHP execution. It supports separate variants for mobile, logged-in users, different user roles, and currency switchers. ### Will Lightify break my site? Lightify is designed with safety in mind. All optimizations can be toggled individually, and exclusion patterns let you skip specific pages or assets. If something looks off, simply disable the relevant feature. ### Does it work with WooCommerce? Yes. Lightify automatically excludes dynamic pages like cart, checkout, and my-account from caching. Currency switcher plugins (Aelia, YITH, WCML) are also supported with separate cache variants. ### How does the preloader work? After a cache purge, Lightify queues all published posts, pages, taxonomy archives, and author archives for preloading. It processes the queue in the background using Action Scheduler, warming your cache so visitors always hit a cached page. ### Can I use Lightify with other caching plugins? Lightify is a complete caching and optimization solution. Using it alongside other caching plugins is not recommended and may cause conflicts. ### Is Lightify compatible with my theme? Lightify is compatible with any WordPress theme, plugin, or configuration — standard sites, e-commerce, membership, forums, and more. It is a standalone plugin that does not require or depend on anything else to function. ### Will it slow down my admin area? No. Lightify’s optimizations only apply to the frontend. The admin area is untouched, and background tasks like preloading run asynchronously via Action Scheduler. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Lightify – All-in-One Cache & Performance Optimizations & Core Web Vitals” is open source software.
