Why Next.js App Router is our standard for high-performance sites

Most marketing sites still ship a blank shell and hope the client can fetch content before a crawler gives up. That is the opposite of how we build at Onixs.

With the App Router, we render portfolio, services, and editorial pages as HTML on the server. Firebase data is read with the Admin SDK in Server Components, never from the browser on first paint.

The result is simple: Googlebot, Meta crawlers, and LinkedIn previews see the same content a person sees, with Core Web Vitals that hold up under real network conditions.
