This is the Svelte 5 framework with its new Runes API, which gives you explicit reactivity through $state, $derived, and $effect instead of the old reactive declarations. The compiler still does the heavy lifting at build time, so you get tiny bundles and fast runtime performance. SvelteKit handles routing, SSR, SSG, and form actions out of the box. The two-way binding with $bindable and the fact that mutating arrays just works without spreading makes state management remarkably simple. If you want a modern reactive framework that compiles away and doesn't ship a virtual DOM, this is the obvious choice. The TypeScript support is solid and the generated types from routes are genuinely helpful.
