Medusa vs Shopify Storefront API
Side-by-side comparison of 2 ecommerce template stacks. Every dimension reflects real production measurements and real trade-offs — no marketing fluff.
Medusa
Medusa v2 is the open-source backend you run yourself. Pair it with a Next.js storefront and you get a fully self-hosted commerce stack with zero platform fees — at the cost of owning the infrastructure. This wins at scale; it loses on launch speed.
What you gain
- Zero platform fees — no Shopify 2-3% or Shopify Plus tiers eating into margin
- Unlimited backend customization — custom pricing, fulfillment, checkout, tax rules, anything
- Typed JavaScript SDK and an open-source admin dashboard (so your ops team has a real UI)
- Commercial team maintains Medusa — not a solo project at risk of abandonment
Trade-offs
- You run a backend now: uptime, backups, patches, upgrades, monitoring
- Realistic production hosting costs $60-300/month (backend + Postgres + Redis + CDN + email)
- Ecosystem is smaller than Shopify's — fewer pre-built integrations
Performance
Median mobile LCP of 2.1s — the fastest in the catalog when ISR is configured correctly on product pages.
SEO positioning
Excellent SEO with full backend control. Best when organic search matters AND you need backend customization Shopify can't provide.
Shopify Storefront API
Headless Shopify gives you the design freedom of Next.js with the operational simplicity of Shopify's backend. It's the middle-ground between a theme and a self-hosted backend — and the right call when you want custom frontend control without running Postgres yourself.
What you gain
- Full design flexibility on the frontend — no Liquid constraints, no theme editor limits
- Checkout happens on Shopify's domain — PCI compliance is entirely Shopify's problem
- Shopify still handles inventory, tax, fulfillment integrations, and fraud detection
- Server-rendered product pages = excellent SEO (you inherit the Next.js advantages)
Trade-offs
- You maintain a separate Next.js deployment on top of Shopify fees
- Shopify Storefront API releases quarterly — budget 1-2 days per quarter for version upgrades
- Frontend-focused Shopify apps (pop-ups, personalization widgets) don't work out of the box and need manual re-integration
Performance
Mobile LCP around 2.3s with the Shopify image CDN handling the heavy lifting. Close to Next.js + Medusa performance without running the backend.
SEO positioning
Excellent SEO — you get Next.js SSR on top of Shopify-hosted catalog data. The best of both worlds for stores where design flexibility AND organic search both matter.
