FluxCache — Edge Cache & Image Optimizer for WooCommerce

FluxCache brings CDN-grade speed to any store. It safely caches catalog, search, and CMS pages at the edge while bypassing cart/checkout. Images are auto-converted to WebP/AVIF, lazy-loaded, and served responsive. A built-in “Performance Badge” shows off your Lighthouse gains.
