The resulting open source project, Vinext, replaces Next.js's Turbopack bundler with Vite to sidestep Vercel platform lock-in and enable easier deployment to Cloudflare Workers and other targets. The AI-generated code was guided by the existing Next.js test suite, though no human has reviewed it yet. Vinext shows promising benchmarks — up to 4.4x faster builds and 56% smaller client bundles than Next.js 16 with Turbopack. Faulkner notes that human oversight was still critical for course-correction, and raises broader questions about AI-generated codebases that no human fully understands. ## Full article daily.dev links to this article rather than hosting it.
