RenderFi Lite speeds up your Shopify store in one click, with no theme code and no DNS changes. It automatically defers heavy third-party scripts (chat, analytics, marketing tags) and lazy-loads off-screen images and content, reducing the interaction delays and layout shifts that affect Core Web Vitals like INP, LCP, and CLS. It also measures your store's real-visitor performance so you can see how your Core Web Vitals change over time.

• One-click install with no theme code or DNS changes.
• Optimizes Core Web Vitals, including INP, LCP, and CLS.
• Real-visitor performance dashboard for your live storefront.
• Compatible with Online Store 2.0 themes, including Dawn.
• No shopper personal data collected.
