SvelteKit is a free, open-source framework built on Svelte with routing, SSR, and deployment adapters. MIT-licensed and free for any project.
SvelteKit is a free, open-source framework for building full web applications using Svelte, adding the routing, rendering, and deployment infrastructure that the Svelte component library alone does not include. It plays a role similar to Next.js for React or Nuxt for Vue.
Svelte was created by Rich Harris and first released in 2016. SvelteKit itself was announced in October 2020, entered beta in March 2021, and reached its 1.0 stable release in December 2022. Rich Harris now works on Svelte full-time as an employee of Vercel, while governance of the open-source project remains independent.
SvelteKit provides file-based routing that maps folder structure directly to application routes, along with built-in data-loading functions and form actions for handling server-side logic. It supports server-side rendering, static prerendering, and client-side rendering, often within the same application.
Development is powered by Vite, giving instant hot module replacement and fast build times. Deployment is handled through adapters for platforms including Vercel, Netlify, Cloudflare, and traditional Node servers, and the framework includes built-in image optimization and full TypeScript support.
SvelteKit is free and open source under the MIT license, with no cost to use for personal or commercial projects and no usage limits imposed by the framework itself.
Any hosting costs come from the deployment platform chosen (such as Vercel or Netlify), not from SvelteKit, which does not sell a paid tier or subscription.
