Svelte is an open-source user interface framework designed to make web development approachable and efficient. It uses a compiler to transform concise components into applications that do minimal work in the browser, letting developers build with familiar technologies such as HTML, CSS, and JavaScript. The project describes itself as “web development for the rest of us” and aims to make creating for the web an enjoyable experience.

Svelte’s offerings include its core framework, SvelteKit for building web applications, a command-line interface, documentation, an interactive tutorial, packages, and a browser-based playground. The site also provides a blog and resources to help developers learn and build with the framework. Svelte has an active community, supported by Svelte Society, which organises events around the world and connects members through local chapters and Discord.

The project is backed by Vercel and donors and maintained by full-time and part-time contributors. Svelte is free to use and distributed under the MIT license
