Your Shopify Bill Just Hit $2,000/mo. Is Medusa.js Your Exit?
If you're a founder watching transaction fees compound faster than revenue, the open-source headless question isn't theoretical anymore.
Choose Shopify if you need a working store within days and prefer managed hosting, payments, and app ecosystem out of the box. Choose Medusa.js if you need full backend ownership, zero per-transaction platform fees, and custom checkout logic -- it requires Node.js developers but gives you complete control over data, pricing, and multi-region architecture.

What is Shopify?
Shopify is the world's largest hosted ecommerce platform powering over 4 million stores. It offers an all-in-one solution with payments, shipping, inventory, and marketing tools. Plans range from $39/mo for small businesses to $2,300/mo for Shopify Plus enterprise.
What is Medusa.js?
Medusa.js is an open-source headless commerce engine built with Node.js. It provides modular building blocks for commerce — products, carts, orders, payments, shipping — with zero transaction fees and full code ownership. Backed by $9M in funding.
Key Differences
Transaction Fees
Shopify charges 0.5-2% on transactions unless you use Shopify Payments. Medusa.js has zero platform transaction fees — you only pay your payment processor (e.g. Stripe at 2.9% + 30c).
Hosting Model
Shopify is fully managed — no servers to maintain. Medusa.js is self-hosted, giving you full control but requiring infrastructure management or a managed hosting provider.
Frontend Flexibility
Shopify uses Liquid templates with limited customisation (or Hydrogen for headless). Medusa.js is headless-first — build with Next.js, Astro, or any frontend framework.
Extensibility
Shopify relies on its app store ecosystem (8,000+ apps). Medusa.js uses a modular plugin system where you write code — more flexible but requires development effort.
Total Cost of Ownership
Shopify has predictable monthly costs but transaction fees add up. Medusa.js is free but requires hosting ($20-200/mo) and developer time. At $50K+/mo revenue, Medusa.js often wins on cost.

Frequently Asked Questions
What is the difference between Shopify and Medusa.js?
Shopify is a fully hosted ecommerce platform with app ecosystem and Shopify Payments. Medusa.js is an open-source, Node.js headless commerce engine with zero transaction fees, modular architecture, and complete code ownership.
Is Medusa.js a good alternative to Shopify?
Yes, for teams with development resources. Medusa.js offers zero transaction fees, full codebase ownership, and modular architecture. Shopify is better if you need a turnkey solution without dedicated developers.
How much does Shopify cost vs Medusa.js?
Shopify plans range from $39 to $2,300/mo plus 0.5-2% transaction fees unless using Shopify Payments. Medusa.js is free and open-source -- you only pay for hosting and infrastructure, typically $20-200/mo.

Yes. Social Animal specialises in ecommerce migrations. We handle product catalogue transfer, order history, customer data, and frontend rebuilds while preserving SEO. Book a free call to discuss your project.
Which has better performance, Shopify or Medusa.js?
Medusa.js with a headless frontend (Next.js or Astro) typically achieves faster page loads and better Core Web Vitals. Shopify Liquid themes are fast out of the box but harder to optimise beyond defaults.
Does Medusa.js support payments like Shopify?
Medusa.js integrates with Stripe, PayPal, and other providers without forcing a specific gateway. Unlike Shopify, there are no additional transaction fees on top of your payment processor costs.
Is Medusa.js really free compared to Shopify?
Medusa.js is open-source with no license or transaction fees, but you pay for hosting, infrastructure, and developer time. Shopify charges $39-$399/month plus 0.5-2% transaction fees unless you use Shopify Payments. For stores processing over $50k/month, Medusa.js often costs less total -- but only if you have engineering resources to maintain it.
Can Medusa.js handle the same features as Shopify without plugins?
Medusa.js ships with core modules for products, orders, carts, customers, and multi-currency out of the box. But features Shopify covers through its app store -- loyalty programs, reviews, advanced analytics -- require custom code or third-party integrations in Medusa. You gain flexibility but lose plug-and-play convenience.
Which is better for headless commerce, Shopify or Medusa.js?
Both work headless, but differently. Shopify offers the Storefront API with rate limits and data access constraints set by Shopify. Medusa.js gives you a fully open REST and JS SDK with no rate limits since you own the server. For teams building custom frontends in Next.js or Nuxt, Medusa.js provides deeper API control.
Do I need a developer to run a Medusa.js store?
Yes. Medusa.js requires Node.js developers for setup, deployment, payment gateway integration, and ongoing maintenance. Shopify requires no developers for basic stores. If your team lacks backend engineering capacity, Shopify or Shopify Plus is the faster, safer choice.
