SvelteKit Development
Svelte-powered applications — smaller bundles, zero virtual DOM overhead, and exceptional performance.
SvelteKit in production
Svelte compiles to vanilla JavaScript — no virtual DOM, no runtime library. SvelteKit applications ship smaller bundles than equivalent React or Vue applications and typically achieve better runtime performance as a result.
What I build with SvelteKit
Marketing sites, interactive dashboards, and applications where bundle size and runtime performance are critical constraints. SvelteKit's file-based routing, server-side rendering, and adapter system make it production-ready for a wide range of projects.
The honest trade-off
Svelte's ecosystem is smaller than React's. If your project depends on a specific React library (complex date pickers, charting, rich text editors), SvelteKit may require custom solutions. For greenfield projects without those dependencies, SvelteKit is often the highest-performance choice available.
Common questions
Is SvelteKit ready for production in 2026?
Yes — SvelteKit 2 is stable and production-ready. Svelte 5 with runes brings a more explicit reactivity model that scales better in large codebases.
How does SvelteKit compare to Next.js on performance?
Svelte compiles away at build time, so there is no runtime framework overhead. For equivalent sites, SvelteKit typically ships 30-60% less JavaScript than Next.js. This translates directly to faster FCP and TTI.
What CMS do you pair with SvelteKit?
Sanity and Contentful both have good SvelteKit support. For simpler content needs I use Supabase directly — it works extremely well with SvelteKit's server-side data loading.
Can you migrate my React app to SvelteKit?
I can, but this is rarely the right move for an existing codebase. The ROI of a full rewrite rarely justifies the cost unless the performance problems are severe. I will give you an honest assessment before recommending it.
Do you use Svelte 4 or Svelte 5?
Svelte 5 for all new projects. The runes syntax is the future of Svelte and the migration from Svelte 4 is straightforward for existing projects.
