Svelte • Web development for the rest of us

attractively thin, graceful and stylish
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. Developers consistently rank Svelte as the framework they’re most excited about using.
Our sister organisation, Svelte Society, organises events around the globe. Find your chapter and join us in our Discord server.
Backed by Vercel and countless donors, developed by full-time and part-time maintainers, Svelte is here to stay.
