Server Components ship less JS — that's the actual win.
Bundle dropped 40% after migrating Pages Router → App Router. Server-fetched data means less client state. The mental model shift took 2 weeks; the productivity payoff is real.
The React framework that became the default for web apps
Next.js 15+ with the App Router and Server Components is the React framework most teams reach for. Server Components reduce client JS, streaming SSR ships pages faster, and the integration with Vercel is unmatched. Trade-off: the App Router learning curve is real, and the framework changes opinionated patterns roughly every 18 months. Best for full-stack React apps that benefit from server-rendered, server-fetched architecture.

Most cohesive React-fullstack story in 2026.
API routes + Server Components + client islands all in one repo. Auth, DB, UI in the same codebase. The framework gets out of my way.
Watch the breaking changes between majors.
Pages → App Router migration cost us a sprint. v15 → v16 might cost another. The framework moves fast; budget for migration work.
