Cloudflare released vinext, a Vite 8/Rolldown-based drop-in reimplementation of the Next.js API surface built by one engineer with AI assistance in one week at a stated cost of $1,100. Production builds on a 33-route test app run in 1.67s vs 7.38s for Next.js 16 with Turbopack, with client bundles shrinking from 168.9 KB to 72.9 KB gzipped. The project achieves ~94% Next.js API coverage with zero source changes required from existing Next.js apps.
