Sveltekit

Compile-Time Optimized Framework for Ultra-Fast Headless CMS Experiences

Overview

SvelteKit is a modern web framework built around the Svelte compiler, shifting much of the work from the browser to build time. This approach eliminates virtual DOM overhead and results in extremely small, fast client bundles. For headless CMS projects, SvelteKit excels at delivering content-rich pages with outstanding performance, low JavaScript payloads, and excellent Core Web Vitals. Its native support for SSR, static rendering, and edge deployments makes it especially well-suited for high-traffic, SEO-critical content platforms.
