Medusa vs Shopify: An Honest Comparison for 2026

We build on both. That is the only reason this comparison is worth reading — most of them are written by people with exactly one thing to sell.

The short version: Shopify is the right default, and Medusa is the right answer when you can name the specific constraint Shopify puts on your business. Everything below is the detail behind that sentence.

The honest summary table

Where Shopify genuinely wins

Time to market. A competent operator launches a real store in a weekend. Medusa cannot do this and will not pretend to.

Operational burden. Shopify handles PCI scope, uptime, security patching, Black Friday scaling and CDN. That is a full-time job you are not doing, and for most teams it is worth more than the fee.

Checkout conversion. Shopify has optimised its checkout across a volume of transactions no individual store will ever see. Shop Pay's accelerated checkout is a genuine, measurable conversion advantage that you cannot replicate.

The ecosystem. Whatever you need — reviews, loyalty, subscriptions, 3PL — someone has built it and it installs in a click. On Medusa, some of those are integrations you write.

Fixed cost at low volume. At $500k GMV, Shopify plus a few apps is cheaper than an engineer thinking about your infrastructure for one week a month.

Where Medusa genuinely wins

Business logic that does not fit a checkout. B2B quoting and approvals, net terms, per-customer contract pricing, split fulfilment across vendors, usage-based billing, regulated per-jurisdiction rules. On Shopify these are Plus-tier scripts or app chains. On Medusa they are workflows — ordinary code, tested and reviewed.

Data modelling. Shopify gives you metafields. Medusa gives you a module with its own tables, its own migrations and its own service, linked to core commerce entities. The difference shows up the day you need to query on that data.

Cost at scale. Shopify's cost scales with revenue; Medusa's scales with traffic, which is far cheaper. Work through the TCO comparison with your own numbers.

Payment freedom. You integrate whoever underwrote you, and you can run two providers simultaneously for failover. For restricted categories this is decisive.

Platform risk. Nobody can suspend a Medusa store. For most merchants this is abstract; for some it is the entire decision.

The cost crossover, with real numbers

A store at $5M GMV on Shopify Advanced with a typical app stack:

Plus transaction fees, which on Shopify Payments are your processing rate — but add roughly 0.5–1.0% if you use an external gateway. On $5M that surcharge alone is $25k–50k a year.

The same store on Medusa:

Which reads as worse until you notice the Shopify figure grows with revenue and the Medusa figure does not — and that the retainer is buying feature development, not rent. At $15M GMV the platform line has tripled and the infrastructure line has barely moved.

Rule of thumb: below $3M GMV, Shopify is almost always cheaper in total. Above $10M with a heavy app stack, Medusa usually is. In between, it depends entirely on how much of your app spend is compensating for platform limits.

Where Shopify Plus changes the maths

Plus starts around $2,300/month and adds checkout extensibility, Shopify Functions, multiple storefronts and better API limits. It closes part of the customisation gap — and it is often the real alternative being weighed, not standard Shopify.

Plus still does not give you: your own database, arbitrary data models with real schemas, payment provider freedom, or immunity from the acceptable use policy. If those are your constraints, Plus does not solve them at any price.

How to decide

Ask three questions.

1. Can you name a specific thing Shopify prevents you doing, and quantify what it costs? If not, stay.
2. Do you have engineering capacity to operate a Node application indefinitely? If not, stay.
3. Is your platform cost growing faster than your margin? If yes, model the crossover honestly.

Two yeses out of three is a real conversation. One is not.

What migrating in either direction actually looks like

We have moved stores both ways, and the asymmetry is instructive.

Shopify → Medusa takes six to ten weeks and is mostly a build: a storefront, custom modules for logic the platform used to approximate, and the integration work. The data migration is the easy part. See the migration guide.

Medusa → Shopify is faster, three to five weeks, and is mostly a subtraction: you are discarding logic that has no home on the destination. The hard conversations are about which capabilities the business gives up.

That asymmetry is the honest summary of the whole comparison. Moving to Medusa buys capability at the cost of responsibility. Moving to Shopify buys simplicity at the cost of capability.

Hybrid options people forget

The choice is not always binary.

Shopify backend, custom storefront. Hydrogen or Next.js against the Storefront API. You get rendering control and keep Shopify's checkout and operations. Good when your constraint is presentation, not logic.

Medusa alongside Shopify. A separate Medusa store for a product line the platform cannot handle — subscriptions, B2B, a restricted category — while the main catalog stays put. Two systems is a real cost, and it is sometimes cheaper than migrating everything.

Shopify Plus with Functions. Before concluding you need to leave, check whether checkout extensibility solves your specific constraint. It closes part of the gap, and it is a much smaller project than a replatform.

The question is never "which platform is better". It is "what is the cheapest thing that removes the constraint we can name".

We have built on both and migrated between them in both directions. If you want an opinion that accounts for your actual numbers, ask us.
