How we rebuilt Next.js with AI in one week

5 hours ago

vinext is a drop-in replacement for Next.js, built on Vite, offering faster builds and smaller client bundles.
It deploys to Cloudflare Workers with a single command and has early benchmarks showing 4x faster builds and 57% smaller bundles.
Next.js has deployment challenges in serverless ecosystems, requiring bespoke tooling and adapters.
vinext reimplements Next.js API surface on Vite, avoiding the fragility of adapting Next.js output.
Early benchmarks show vinext builds 1.6x to 4.4x faster than Next.js, with significantly smaller bundle sizes.
vinext supports Cloudflare Workers deployment with features like KV caching and ISR out of the box.
Traffic-aware Pre-Rendering (TPR) is introduced to optimize pre-rendering based on actual traffic data.
The project was completed in under a week by one engineer directing AI, costing about $1,100 in tokens.
AI was used extensively, with guardrails like tests and code reviews to ensure quality.
vinext is experimental but has extensive test coverage and early real-world usage.
