Before comparing these three
All three require you to run (or pay for a managed version of) a complete commerce engine — products, inventory, orders, payments, from the ground up. If you already have a working store on Wix, Shopify, or Webflow, that's a different decision than the one this page answers — see the last section.
1. At a glance
| Engine | Stack | Model | Best fit |
|---|---|---|---|
| Medusa | Node.js / TypeScript | Open-source, self-host or cloud | JS/TS teams wanting full backend control |
| Saleor | Python / GraphQL | Open-source, self-host or cloud | Teams wanting a GraphQL-first API surface |
| commercetools | Proprietary, API-first | Fully managed, enterprise contract | Large orgs, dedicated commerce engineering teams |
2. What you're actually signing up for
The honest framing most comparison pages skip: choosing any of these three means choosing to own a commerce backend, not just a frontend. That includes payment provider integration, tax logic, fraud handling, and inventory correctness under concurrent writes — the same category of hard problems every established platform (Shopify, Wix, Webflow) has already solved and hardened in production for years. Medusa and Saleor give you real flexibility in exchange for taking that on yourself; commercetools gives you an enterprise-grade managed version of the same trade, at enterprise pricing and implementation complexity.
3. Medusa
Open-source, Node.js/TypeScript, MIT-licensed. The strongest fit for teams already comfortable in the JS/TS ecosystem who want to self-host (or use Medusa's managed cloud) and retain full control over business logic. Active community, modular plugin architecture, genuinely good documentation. The trade-off is the same as any self-hosted system: you own uptime, scaling, and security patching unless you pay for the managed tier.
4. Saleor
Open-source, Python backend, GraphQL-first API. A strong pick if GraphQL is your team's default and you want that consistency from your commerce layer too. Similar self-host-or-cloud model to Medusa, with a smaller but active community and a comparable engineering commitment required to run in production.
5. commercetools
Not open-source — a fully managed, API-first commerce platform built for enterprise scale. Composable architecture, strong multi-brand/multi-region support, and a track record with large retailers. The realistic entry point is a systems integrator engagement and enterprise-tier pricing; this is rarely the right choice below a dedicated commerce engineering team and a multi-million-dollar revenue base.
6. What about Alokai (formerly Vue Storefront)?
Worth naming directly: Alokai is the closest thing to a bridge-layer product among the well-known names in this space — "Frontend as a Service" middleware connecting a custom frontend to an existing backend (SAP Commerce Cloud, commercetools, BigCommerce, Magento) without replatforming. If a comparison page is going to be honest about the landscape, that positioning deserves a mention.
The practical differences: Alokai targets large, primarily enterprise/BigCommerce-and-Magento-shaped deployments, with no public pricing and an implementation path that runs through professional services. Trama targets Wix, Shopify, and Webflow specifically, ships a free tier and a self-serve SDK on npm, and a working preview in under a minute — no sales conversation required to see it connected to a real store. Same underlying idea; a very different starting point depending on team size and which backend is actually in play.
7. The fourth option: don't replace what already works
All three platforms above solve the same underlying problem — "I want a modern, API-first commerce backend" — by having you build or operate one from scratch. If you already have a working Wix, Shopify, or Webflow store, that backend already exists, is already handling payments and inventory correctly, and doesn't need replacing. A bridge layer like Trama gets you the same custom-frontend outcome — full design freedom, a real GraphQL/REST data layer, no theme constraints — without the migration, the new backend to operate, or the payments/tax/fraud problem space to re-solve from zero.
8. Frequently asked questions
What is the difference between Medusa, Saleor, and commercetools?
Medusa is a Node.js/TypeScript open-source commerce engine you self-host or deploy via their cloud, aimed at developers wanting full backend control. Saleor is a Python/GraphQL open-source engine with a similar self-hosted-or-cloud model. commercetools is a fully managed, enterprise-grade commerce platform (API-first, not open-source) aimed at large organizations with dedicated engineering teams and bigger budgets.
Is Medusa free?
The core engine is open-source and free to self-host. Medusa also offers a managed cloud option with usage-based pricing if you don't want to run your own infrastructure.
Is commercetools worth it for a small team?
Rarely. commercetools pricing and implementation complexity are built for enterprise scale — it typically requires a systems integrator or dedicated commerce engineering team. Small and mid-size teams usually get more value from Medusa, Saleor, or staying on an existing platform (Shopify, Wix, Webflow) with a bridge layer.
Do I have to choose one of these to go headless?
No. All three require you to run (or pay to run) a full commerce engine — products, inventory, orders, payments — from scratch or via their cloud offering. If you already have a working Wix, Shopify, or Webflow store, a bridge layer gets you a headless frontend without replacing the backend at all.
How is Trama different from Alokai (Vue Storefront)?
Both bridge a custom frontend to an existing backend without replatforming. Alokai targets large deployments on SAP Commerce Cloud, commercetools, BigCommerce, and Magento, with no public pricing and an implementation path through professional services. Trama targets Wix, Shopify, and Webflow specifically, with a free tier, a self-serve SDK, and a working connected preview in under a minute — no sales process required.
