About Svelte
Svelte is a UI framework that uses a compiler to turn components into efficient JavaScript. You write components with the HTML, CSS and JavaScript you already know.
What it does
Svelte moves most of the work into a build step. The compiler reads each component and produces lean code, so the browser has less to run when a page loads and updates. Components tend to stay short because much of the wiring between data and screen is handled for you.
Key features
- Components written in HTML, CSS and JavaScript
- Compiled output with minimal runtime code
- SvelteKit companion for full applications
- Online playground for trying code in the browser
Who it's for
Developers who like a small, readable component style and want a fast result on the web. Teams building content sites, interactive tools or full applications can all use it, especially when they want less code to ship.
Pricing and good to know
Svelte is free and open source software released under the MIT license. It runs in the browser and is usually paired with SvelteKit for routing and server features. Projects that rely on a particular library should check that it is available for Svelte before they start.
