| Pros | Free, lightweight and simple to configure; Static HTML page cache with cache expiry and automatic clearing; WP-CLI commands and Gzip or Brotli pre-compression | Bulk and on-upload image compression at no cost; Lazy loading for images and embedded video; Works with common page builders, WooCommerce and caching plugins |
| Cons | Small feature set; no object cache or database cleanup; Browser caching is limited to 304 revalidation; WebP rewriting assumes the .webp files already exist | WebP, AVIF, resizing and the image CDN need Smush Pro; Images are sent to the WPMU DEV API for compression |
