TanStack Start Has a Free Full-Stack Framework: Type-Safe Routing, Server Functions, and Full-Document SSR

TanStack Router proved that routing can be fully type-safe — every param, search query, and loader return type checked at compile time. But it was client-only. What if you got that same type safety across the full stack? Server functions, SSR, streaming — all with end-to-end TypeScript inference? That's TanStack Start. What TanStack Start Gives You 100% type-safe routing — route params, search params, loader data — all inferred Server functions — call backend code from components with createServerFn Full-document SSR — server renders the complete HTML document, not just React Streaming — progressive rendering with Suspense boundaries Search params as state — URL search params are first-class, validated state Framework agnostic goal — React first, other frameworks planned Quick Start npx create-start@latest my-app cd my-app && npm install && npm run dev Type-Safe Route Params // src/routes/users/$userId.tsx import { createFileRoute } from " @tanstack/react-router " ; export const Route
