App Router Foundation
The most comprehensive App Router starter available. The architecture done right.
Deloryen Studio
The Next.js App Router is not an upgrade — it is a new architecture. Server components, streaming, nested layouts, and the generateMetadata API change how applications are built at the fundamental level. Templates still built on the Pages Router are legacy products regardless of their label. Every Deloryen template is App Router native: server components by default, client components only where interactivity requires it, route groups for clean organization, and the metadata API generating unique titles, descriptions, and structured data for every page. This is the architecture that Google, Vercel, and the Next.js team are actively developing. It is the only foundation worth building on in 2025.

FAQ
The App Router (introduced in Next.js 13, stable in 13.4) uses React Server Components by default, supports streaming, and uses nested layouts. The Pages Router is the legacy architecture. Server components render on the server and send HTML, dramatically reducing JavaScript sent to the browser and improving performance.
Yes. All Deloryen templates released from 2024 onward are built exclusively on the App Router. No Pages Router code is present.
The generateMetadata function allows dynamic, per-page metadata generation with full TypeScript support. Titles, descriptions, canonical tags, Open Graph, and structured data are all generated server-side and present in the initial HTML response — not injected by JavaScript.
Yes. Data fetching uses native fetch with Next.js cache semantics, compatible with Vercel Edge deployment. No getServerSideProps or getStaticProps — these are Pages Router patterns.
