One engineer used AI to rebuild Next.js on Vite in a week. vinext builds up to 4x faster, produces 57% smaller bundles, and deploys to Cloudflare Workers with a single command.

Last week, one engineer and an AI model rebuilt the most popular front-end framework from scratch. The result, vinext (pronounced “vee-next”), is a drop-in replacement for Next.js, built on Vite, that deploys to Cloudflare Workers with a single command. In early benchmarks, it builds production apps up to 4x faster and produces client bundles up to 57% smaller.

    I wonder if there are tests that check that it is 100% compatible and not like 97%

    Edit: ah, not even 97%

    That said, the test suite is extensive: over 1,700 Vitest tests and 380 Playwright E2E tests, including tests ported directly from the Next.js test suite and OpenNext’s Cloudflare conformance suite. We’ve verified it against the Next.js App Router Playground. Coverage sits at 94% of the Next.js 16 API surface
