Vercel now supports React Router v7 applications when used as a framework:

import { vercelPreset } from "@vercel/react-router/vite";
import type { Config } from "@react-router/dev/config";
export default {
  ssr: true,
  presets: [vercelPreset()],
} satisfies Config;

This includes support for server-rendered React Router applications using Vercel's Fluid compute. Further, the Vercel preset intelligently splits application bundles across Vercel Functions, and supports custom server entry points.
