SvelteShop pairs SvelteKit’s rendering speed with Medusa.js’s headless commerce engine. The result is a storefront that loads fast, looks good, and gives you full control over the shopping experience.
Product pages come with image galleries, variant selectors (size, color), inventory tracking, and structured data for SEO. The cart persists across sessions, and the checkout flow handles address entry, shipping calculation, and Stripe payment in a clean multi-step form.
What stands out
Performance. SvelteKit’s server-side rendering combined with aggressive image optimization means product pages consistently score 95+ on Lighthouse. For ecommerce, where every 100ms of load time affects conversion, this matters.
The Medusa integration is thorough — it’s not just fetching products. Order management, discount codes, gift cards, and customer accounts are all wired up.
Where it could improve
Running Medusa requires a separate Node server and Postgres database. This isn’t a “deploy to Vercel and forget” situation. You’ll need Railway or a VPS for the backend.
Payment options are Stripe-only. If you need PayPal, Klarna, or local payment methods, you’ll integrate those yourself through Medusa’s plugin system.
