Overview

What is SvelteKit?

SvelteKit is the official full-stack web framework for Svelte. It provides file-based routing, server-side rendering, static site generation, and API routes — all powered by Svelte's compile-time reactivity model. Known for producing the smallest bundle sizes and best runtime performance of any major framework.
