In plain English

SvelteKit is the official application framework for building web applications with Svelte. While Svelte is a component library for building UI pieces, SvelteKit is the full-stack framework that adds routing, server-side rendering, static site generation, and deployment tooling on top of it. Its tagline is "web development, streamlined." The repository is a monorepo containing the core @sveltejs/kit package alongside a set of adapters that let you deploy a SvelteKit app to different hosting environments: adapter-auto detects the platform automatically, while dedicated adapters exist for Cloudflare, Netlify, Vercel, Node.js servers, and static file hosting. Additional community-maintained adapters are listed on the Svelte Society website. The repo also includes packages for AMP support, enhanced image handling, and library packaging. SvelteKit uses Vite as its underlying build tool. The project is MIT-licensed and sustained by volunteer contributors, with financial support available via Open Collective.
