Svelte is a UI framework that uses a compiler to let you write breathtakingly concise components that do minimal work in the browser, using languages you already know — HTML, CSS and JavaScript. It’s a love letter to web development. But don’t take our word for it.
Head over to the playground to see examples, create your own Svelte apps in the browser, and share them with other people. I’m a Large Language Model (LLM)
Welcome to the Svelte tutorial! This will teach you everything you need to know to easily build web applications of all sizes, with high performance and a small footprint.
The Svelte team maintains a VS Code extension, and there are integrations with various other editors and tools as well. You can also check your code from the command line using sv check.
Svelte has a large and robust ecosystem of component libraries that you can use in your applications such as shadcn-svelte, Skeleton, and Flowbite Svelte. But you don’t have to wait for these libraries to upgrade to Svelte 5 in order to upgrade your own application.
What is Svelte? In short, Svelte is a way of writing user interface components — like a navigation bar, comment section, or contact form — that users see and interact with in their browsers.
These pages serve as reference documentation. If you’re new to Svelte, we recommend starting with the interactive tutorial and coming back here when you have questions. You can also try Svelte online in the playground or, if you need a more fully-featured environment, on StackBlitz.
It lists the project’s dependencies — including svelte and @sveltejs/kit — and a variety of scripts for interacting with the SvelteKit CLI. (We’re currently running npm run dev in the bottom window.)
We're proud that Svelte was recently voted the most admired JS web framework in one industry survey while drawing the most interest in learning it in two others.
