SvelteKit
The official application framework for Svelte
Overview
SvelteKit is to Svelte what Next.js is to React - the full-stack framework that handles routing, SSR, data loading, and deployment. It brings Svelte's compilation advantages to full applications, with file-based routing and a server that runs alongside your client code.
The load function pattern is elegantly simple. Each page can define a load function that runs on the server, fetches data, and passes it to the component. No useEffect chains, no loading state management - just a function that returns data and a component that receives it.
SvelteKit's adapter system lets you deploy to any platform - Vercel, Netlify, Cloudflare Workers, Node.js, or even static hosting. Write your app once and deploy anywhere, with the adapter handling platform-specific optimizations.

Why We Recommend SvelteKit
SvelteKit delivers the best performance-to-complexity ratio of any full-stack framework. For projects where page speed is a competitive advantage, SvelteKit consistently produces the fastest results.
