What You Get

First Contentful Paint (FCP) measures how fast users see your first content. Render-blocking CSS and JS delay FCP — making pages feel slow even on fast connections. We extract the above-the-fold CSS, inline it in <head>, load the full stylesheet asynchronously, and eliminate render-blocking JavaScript. The result: users see your content immediately, before any external resources load.
