Flash Page Speed Optimizer speeds up your shop's loading process without any code or themes. How? By improving your Google PageSpeed Score, real users' CrUX metrics, and Core Web Vitals scores like TBT, LCP, and CLS through deferred scripts from third-party vendors, lazy image and iframe loading, and reduced render-blocking resources. Check before and after speed scores for your store in the dashboard, add critical scripts, and disable optimization whenever you want.

• Optimize Page Speed and Core Web Vitals (LCP, CLS, TBT) on mobile & desktop
• Check before-and-after Google PageSpeed scores inside the app
• One-click setup with no code or manual theme edits
• Choose which pages are optimized, with on/off control anytime
