Cloudflare vibe codes 94% of Next.js API 'in one week'

"Vercel will use the same adapter API as every other partner. The Next.js team is addressing this following numerous complaints that deploying the framework with full features on platforms other than Vercel is too difficult, with a feature in progress called deployment adapters."

"If you want to deploy it to Cloudflare, Netlify, or AWS Lambda, you have to take that build output and reshape it into something the target platform can actually run. The Next.js tooling is entirely bespoke, according to Cloudflare engineering director Steve Faulkner."

"I spent a couple of hours going back and forth with Claude in OpenCode to define the architecture. Almost all the code was written by AI, Faulkner said, starting with a plan for the Vinext project using Vite build tool in place of Turbopack."

Cloudflare developed Vinext, an experimental open-source project using AI to implement 94% of the Next.js API with Vite instead of Turbopack. The initiative addresses difficulties deploying Next.js on platforms beyond Vercel. Next.js uses a bespoke toolchain that requires reshaping build output for different platforms. While Next.js deployment adapters are in progress, they remain insufficient due to reliance on Turbopack and limited platform-specific API support during development. OpenNext, an existing conversion tool, proved fragile due to unpredictable Next.js version changes. Cloudflare's AI-driven approach spent approximately $1,100 on Claude tokens to define architecture and generate code, offering a potential solution to the framework's portability challenges.
