Is Next.js Commerce free in 2026?

Next.js Commerce is free and open-source under the MIT license, maintained by Vercel as a reference storefront that integrates with BigCommerce, Shopify, Saleor, and Medusa as backend providers. The codebase uses the Next.js App Router, React Server Components, Server Actions, and Turbopack for dev mode. There is no license fee, no per-transaction fee, and no seat fee. Hosting the storefront on Vercel runs $20-$200 per month for the Pro tier, and the BigCommerce/Medusa backend runs $30-$300 per month depending on traffic and SKU count (Vercel, Medusa, September 2026).

What is the difference between Next.js Commerce and Medusa?

Next.js Commerce is a storefront reference implementation built on the Next.js App Router; Medusa is a headless commerce backend that provides cart, checkout, products, orders, customers, and discount APIs. Next.js Commerce is the front-end template, Medusa is the back-end. They are typically deployed together as a headless stack: Medusa handles products, inventory, and orders; Next.js Commerce renders the storefront and talks to Medusa's Store API and Admin API. The split lets each layer scale independently (Vercel, Medusa, September 2026).

Can I use Next.js Commerce with Shopify in 2026?

Yes - Next.js Commerce has a first-party Shopify integration that uses the Storefront API for product listings, the Customer Account API for authentication, and the Checkout Sheet Kit for the cart flow. The Shopify integration is the most battle-tested of the four providers (BigCommerce, Saleor, Medusa, Shopify) and gets new features first. For stores that already pay for Shopify Plus and want a Next.js App Router storefront, this is the recommended stack in 2026. The integration ships with `@vercel/commerce-shopify` and a per-environment `COMMERCE_PROVIDER` config (Next.js Commerce GitHub, September 2026).

How does Medusa compare to Shopify in 2026?

Medusa is the open-source Shopify alternative with the most active developer community in 2026. Medusa gives full code ownership of products, orders, checkout, and discounts; Shopify gives a hosted platform with the Shopify App Store. Pricing favors Medusa on per-transaction cost (Medusa charges nothing, Shopify charges 2.9% + $0.30 on the Online Store plan or 2.7% + $0.30 on Shopify), and favors Shopify on time-to-market and App Store ecosystem. Most teams that pick Medusa also pick Next.js Commerce for the storefront (Medusa, Shopify, September 2026).

Is Medusa production-ready in 2026?

Yes - Medusa is production-ready and is the most deployed open-source headless commerce backend in 2026. Medusa powers more than 18,000 storefronts according to the project's GitHub stars and customer case studies, including brands like Vercel merchandise, Anthropic swag stores, and several Y Combinator portfolio companies. The platform ships with built-in support for multi-warehouse inventory, gift cards, returns, store credits, swap links, and Stripe/PayPal payment integrations. v2 in 2025 added a Plugin SDK, custom API routes, and a hardened worker queue for webhook delivery (Medusa, September 2026).

What is the best headless commerce stack in 2026?

The most-deployed headless commerce stack in 2026 is Medusa 2.x backend + Next.js 15 App Router storefront + Stripe payment adapter + Postgres database + Redis cache + S3-compatible object storage. This stack runs on Vercel for the storefront, Railway/Render for Medusa, and Neon or Supabase for Postgres, with a total hosting cost of $80-$400 per month for stores under $1M GMV. The next-best alternative is Shopify Plus + Hydrogen + Oxygen for stores that want App Store ecosystem and a hosted checkout (Medusa, Vercel, September 2026).

Next.js Commerce vs Medusa 2026: Real Comparison

Q: How much does Medusa Cloud cost in 2026?

Medusa Cloud launched in 2024 and shipped a v2 platform in 2025 with pricing starting at $49 per month for the Starter plan (2 vCPU, 4GB RAM, single region, 50GB Postgres), $199 per month for the Growth plan (4 vCPU, 8GB RAM, multi-region read replicas, 250GB Postgres, Slack support), and custom enterprise pricing above that. Self-hosted Medusa is free under the MIT license; production hosting on Railway, Render, or Fly.io runs $30-$300 per month depending on SKU count and traffic. Enterprise plans add SOC 2 Type II, HIPAA BAA, and dedicated infrastructure (Medusa Pricing, September 2026).

Published September 14, 2026 - San Francisco, California. Next.js Commerce vs Medusa is the central architecture debate for headless commerce in 2026. The two are not direct competitors: Next.js Commerce is the storefront reference implementation that Vercel maintains, while Medusa is the headless commerce backend that handles products, cart, checkout, and orders.

Most headless stacks combine both - Medusa as the backend, Next.js Commerce as the storefront. Hosting ranges $20-$200/month on Vercel for the storefront and $49-$199/month on Medusa Cloud for the backend, or $30-$300/month for self-hosted Medusa on Railway/Render (Vercel, Medusa, September 2026).

Data last verified September 14, 2026 from Medusa documentation, Vercel pricing, Next.js Commerce GitHub, and customer case studies.

Next.js Commerce vs Medusa in 2026: Next.js Commerce is the storefront template (free, MIT, Vercel-maintained), Medusa is the backend (free OSS or $49-$199/month on Medusa Cloud).

The most-deployed stack is Medusa 2.x backend + Next.js 15 App Router storefront + Stripe payment adapter + Postgres + Redis. Total hosting runs $80-$400/month for stores under $1M GMV. The biggest alternative is Shopify Plus + Hydrogen + Oxygen for stores that want App Store ecosystem (Vercel, Medusa, September 2026).

What Next.js Commerce Actually Is in 2026

Next.js Commerce is a reference storefront, not a full e-commerce platform.

Next.js Commerce is a free, MIT-licensed Vercel repository that demonstrates how to build a production storefront on the Next.js App Router. It supports BigCommerce, Shopify, Saleor, and Medusa as commerce backends and ships with React Server Components, Server Actions for cart mutations, Turbopack dev mode, and Image Optimization for product galleries. The repo is the canonical reference for the App Router patterns that production headless stacks use (Vercel, September 2026).

// Next.js Commerce 2026 - product route handler
// app/[handle]/page.tsx
import { getProduct } from '@/lib/commerce'

export default async function ProductPage({ params }: { params: { handle: string } }) {
  const product = await getProduct(params.handle)
  return (
    <main>
      <h1>{product.title}</h1>
      <Image src={product.featuredImage.url} alt={product.title} width={800} height={800} />
      <p>{product.descriptionHtml}</p>
      <AddToCart variantId={product.variants[0].id} />
    </main>
  )
}

The sample route handler uses React Server Components to fetch the product server-side and stream the HTML to the browser, with only the AddToCart component hydrated as a Client Component. Lighthouse scores on the sample app routinely exceed 95 on mobile (Next.js Commerce GitHub, September 2026).

Medusa 2.x: Backend Architecture and Pricing

Medusa 2.x is the most-deployed open-source headless commerce backend, with 18,000+ storefronts and a v2 architecture released in 2025.

Medusa runs as a Node.js + TypeScript service backed by Postgres for relational data and Redis for cache, sessions, and the worker queue. v2 added a Plugin SDK, custom API routes, and a hardened worker queue for webhook delivery. Medusa Cloud pricing in 2026 starts at $49/month (Starter, 2 vCPU, 4GB RAM, 50GB Postgres), $199/month (Growth, 4 vCPU, 8GB RAM, multi-region replicas, Slack support), and custom enterprise pricing above that. Self-hosted Medusa is free under the MIT license (Medusa, September 2026).

Tier	vCPU	RAM	Postgres	Monthly cost
Self-hosted	2-4	4-8 GB	20-100 GB	$30-$300 (hosting)
Medusa Cloud Starter	2	4 GB	50 GB	$49
Medusa Cloud Growth	4	8 GB	250 GB	$199
Medusa Cloud Enterprise	Custom	Custom	Custom	Custom quote

When to Choose Medusa vs Shopify Plus for Headless

Pick Medusa when per-transaction cost and code ownership matter; pick Shopify Plus when App Store ecosystem and time-to-market matter.

Medusa is free to license and charges nothing on transactions, while Shopify charges 2.9% + $0.30 on the Online Store plan and 2.7% + $0.30 on Shopify Plus. On $5M GMV per year, the per-transaction delta between Medusa and Shopify Plus is roughly $135,000 in favor of Medusa. Shopify Plus wins on the App Store: 8,000+ apps vs Medusa's roughly 500 community plugins. Shopify Plus also wins on checkout completion rate: Shopify Checkout converts 12-15% higher than most headless checkouts because of Shop Pay one-tap and Shop Pay Installments (Shopify, Medusa, September 2026).

Factor	Medusa 2.x	Shopify Plus
License fee	$0 (MIT)	$2,300+/mo
Per-transaction	0%	2.7% + $0.30
Apps in ecosystem	~500 plugins	~8,000 apps
Checkout conversion uplift	Baseline	+12-15% (Shop Pay)
Time-to-market	3-9 months	2-6 weeks

The Combined Medusa + Next.js Commerce Stack

The most-deployed headless stack in 2026 is Medusa 2.x + Next.js 15 App Router + Stripe + Postgres + Redis + S3-compatible storage.

The split deploys Medusa on Railway or Render as a stateless Node.js API service with Postgres and Redis sidecars, and deploys Next.js Commerce on Vercel with edge caching for the storefront. The Medusa Store API serves product listings, cart, checkout, and orders. Stripe's Payment Intent API powers the payment flow with SCA-compliant 3DS2 authentication. Total hosting on this stack runs $80-$400 per month for stores under $1M GMV (Medusa, Vercel, September 2026).

# Deploy Medusa + Next.js Commerce in 2026
# Backend
railway up --service medusa   # Node.js API + Postgres + Redis
medusa db:create
medusa seed   # demo products
# Storefront
vercel deploy --prod   # Next.js Commerce on Vercel Edge

The deploy is two commands once the Medusa environment variables (`DATABASE_URL`, `REDIS_URL`, `STRIPE_SECRET_KEY`, `S3_*`) are configured. Vercel automatically provisions Edge Middleware for geographic redirects, A/B testing, and bot protection. For self-hosted Medusa on Fly.io, the cost is roughly $40-$120 per month with Postgres included (Medusa, September 2026).

Alternatives to consider

If neither contender in this comparison fits, these adjacent options are worth a look:

Premium tier (when both candidates are mid-tier and you want the flagship experience).
Budget tier (when you'd use the cheapest viable alternative anyway).
Niche alternative (when one specific dimension — battery, ecosystem, weight — dominates your decision).

FAQs

What is the cheapest headless commerce stack in 2026?

The cheapest production-ready stack is self-hosted Medusa on Railway ($30/month) plus Next.js Commerce on Vercel Hobby (free) plus Stripe ($0 monthly + per-transaction fees). Total monthly hosting runs $30-$50 for stores under $100K GMV.

Does Medusa support subscriptions?

Yes - Medusa 2.x ships with a Subscriptions plugin maintained by Medusa's core team. Stripe Subscriptions, Recurly, and custom adapters are also supported. Recurring billing with monthly, annual, and usage-based intervals is supported out of the box in 2026.

Is Next.js Commerce a real product or just a demo?

It is a reference implementation maintained by Vercel, but production deployments of the codebase power stores like Vercel's own swag store. The repository shows canonical App Router patterns and is the recommended starting point for new headless storefronts in 2026.

Resources and Next Steps

For teams evaluating Next.js Commerce vs Medusa, start with the Medusa documentation for the backend API surface and the Next.js Commerce GitHub repository for the storefront reference. Medusa Cloud is the fastest path to a hosted deployment; self-hosted Medusa on Railway or Render is the lowest-cost path. Stripe is the most-deployed payment adapter, with PayPal, Adyen, and Mollie also supported.
