Svelte

svelte.dev
Open source

Svelte is an innovative, free, and open-source front-end compiler created by Rich Harris and maintained by the Svelte core team. Unlike traditional frameworks that do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app. The result is highly optimized vanilla JavaScript that updates the DOM efficiently. Svelte offers a component-based architecture, reactive declarations, and built-in state management, all with a remarkably small runtime footprint. Its simplicity and performance make it an attractive option for building fast, scalable web applications with less boilerplate code.
