FlyingPress is a performance plugin for WordPress, the open-source content management system, made by FlyingWeb LLC. A plugin is an add-on installed inside a WordPress site. This one speeds up pages mainly through caching: it stores a ready-made copy of each page so that the server does not rebuild it for every visitor.
After installation and license activation, one dashboard controls page caching (with preloading and a refresh when content changes), page optimization, image optimization and Redis object caching, which reuses database results on hosts that support Redis. For page optimization, FlyingPress cloud servers render each page in a real browser and find the critical CSS that must load first; the rest is deferred. Images are compressed and served as WebP or AVIF. The plugin also measures Core Web Vitals, Google's metrics for loading speed, responsiveness and visual stability, from real visitors, and keeps WooCommerce cart and checkout pages dynamic.
It is a commercial plugin sold as a yearly subscription by number of sites, with every feature in every plan and a 14-day free trial.
