Inside Cloudflare Vinext: a from-scratch Next.js App Router rebuild

Inside Cloudflare Vinext: A Ground-Up Rebuild of the Next.js App Router Cloudflare has introduced Vinext , a full reimplementation of the Next.js App Router built entirely on Vite. This is not a wrapper or adapter around Next.js. It’s a clean-room rebuild of the App Router surface area — including file-based routing, React Server Components (RSC) streaming, and server actions — implemented on top of Vite instead of the original Next.js toolchain. Reported Performance Improvements Cloudflare claims the following improvements: 4.4× faster production builds 57% smaller client-side bundles 94% coverage of the Next.js 16 App Router API The migration path is intentionally minimal. Instead of running next , you run vinext . Your existing project structure remains the same: app/ directory next.config.js Existing components and routing patterns No restructuring required.
