You've been running your store on a traditional platform for two years. Sales are fine — maybe $15k a month — but every time you want to change the homepage layout or add a custom checkout step, you're waiting on a developer or fighting a theme editor that wasn't built for what you need. Someone in a Facebook group mentions "going headless," and suddenly you're down a rabbit hole of API docs and architecture diagrams wondering if this is even for you.
Here's the honest answer: it might be, and it might not be. But you won't know until you understand what a headless commerce platform actually does, what the real tradeoffs are, and how the major options compare at the scale most small stores actually operate. That's exactly what this headless commerce platform comparison is built to do.
What "Headless" Actually Means (Plain English)
A traditional e-commerce platform bundles your storefront (what shoppers see) and your backend (inventory, orders, payments) into one package. You get speed and simplicity, but the two sides are tightly coupled — change one, and you risk breaking the other.
Headless commerce separates those two layers. Your backend — the commerce engine — exposes data through an API. Your frontend — the site your customers actually visit — is built independently and pulls that data on demand. Think of it like a restaurant kitchen (backend) and a dining room (frontend) that can be redesigned without touching the stoves.
The payoff: you can build faster, more custom storefronts, run the same backend across a mobile app and a website simultaneously, and swap out either layer without starting over. The cost: more moving parts, more decisions, and usually a higher baseline technical investment.
Why Small Stores Are Looking at This Now
Three things have made headless realistic for stores under $2M ARR in the last couple of years:
- Hosted headless options dropped the infrastructure burden. You no longer have to spin up your own servers to go headless. Platforms like Medusa (self-hostable but cloud-friendly) and Commerce Layer handle the heavy lifting.
- Frontend frameworks got friendlier. Next.js starter kits now exist for most major commerce backends. A developer who knows React can have a working storefront in a weekend.
- The cost of staying on a rigid platform got more visible. When Shopify raised its fees in 2023 and again adjusted its app ecosystem terms, a lot of store owners started doing the math on lock-in.
If you're hitting a wall on customization, running a content-heavy brand where your blog and store need to feel like one thing, or selling across multiple channels simultaneously, headless is worth a serious look.
Headless Commerce Platform Comparison: The Main Contenders
Here are the platforms that come up most often in conversations with SMB operators, with the numbers and tradeoffs that actually matter at your scale.
Shopify Plus with Hydrogen
Best for: Stores already on Shopify with $500k–$5M ARR that want headless without migrating their backend.
Shopify's Hydrogen is a React-based framework that lets you build a custom frontend on top of Shopify's commerce engine. You keep your existing products, orders, and checkout infrastructure. The Oxygen hosting layer (included with Plus) deploys your Hydrogen storefront on Shopify's CDN.
- Cost: Shopify Plus starts at $2,300/month. That's a real number — budget for it.
- Dev effort: Medium-high. You'll need a developer comfortable with React and GraphQL. Expect 4–8 weeks for a solid initial build.
- Lock-in level: High. Your frontend is portable, but your data stays in Shopify.
- Upside: If you're already on Shopify, your catalog, apps, and checkout logic don't move. The learning curve is on the frontend only.
A candle brand I know with about 8,000 SKUs moved to Hydrogen after their theme hit a performance ceiling. Their Lighthouse score went from 54 to 91 after the migration. Conversion lifted 11% in the first 90 days. The project cost them roughly $18,000 in dev time.
Medusa.js
Best for: Technical founders or stores with a developer on staff who want full control and zero platform fees.
Medusa is an open-source Node.js commerce engine. You self-host (or deploy to Railway, Render, or a VPS) and build your frontend however you like — Next.js, Astro, whatever fits. There are no per-transaction fees and no monthly platform cost beyond your hosting bill.
- Cost: Hosting runs $20–$150/month depending on traffic. Dev setup is the real investment — budget 2–4 weeks for a developer to configure a production-ready instance.
- Dev effort: High upfront, low ongoing once it's running.
- Lock-in level: Near zero. You own the code and the database.
- Upside: Total flexibility. Medusa's plugin ecosystem covers payments (Stripe, PayPal), fulfillment (ShipBob, EasyPost), and CMS integrations out of the box.
The tradeoff is support. When something breaks at 11pm, you're reading GitHub issues, not calling a help desk. That's fine if you have a developer. It's a real risk if you don't.
Commerce Layer
Best for: Brands selling across multiple regions or channels that need a clean API-first backend without managing infrastructure.
Commerce Layer is a headless commerce API that handles pricing, inventory, orders, and payments — nothing else. You bring your own frontend and your own CMS. It's built for multi-market setups: you can run different prices, currencies, and tax rules per market from one backend.
- Cost: Free tier up to 1,000 orders/month. Paid plans start at $649/month for higher volume.
- Dev effort: Medium. The API is well-documented; most teams get a prototype running in a few days.
- Lock-in level: Low-medium. Your frontend is fully portable; migrating away from Commerce Layer means rebuilding your order logic, which is non-trivial.
- Upside: Exceptional for international stores. If you're selling in three currencies with different tax rules, Commerce Layer handles that in a way that would take months to build yourself.
Vendure
Best for: Stores that want open-source flexibility but prefer TypeScript and a more opinionated structure than Medusa.
Vendure is a TypeScript/Node.js headless commerce framework. It's less widely known than Medusa but has a strong plugin ecosystem and a well-designed admin UI out of the box. Like Medusa, you self-host.
- Cost: Free (open source). Hosting is similar to Medusa — $30–$200/month.
- Dev effort: High. TypeScript knowledge is a must.
- Lock-in level: Near zero.
- Upside: The built-in admin panel is genuinely good — better than Medusa's default out of the box, in most developers' opinion. Faceted search and complex product variants are handled cleanly.
BigCommerce (Headless)
Best for: Stores that want a SaaS backend with headless flexibility, without committing to Shopify's ecosystem.
BigCommerce has offered headless APIs for a few years now and actively markets to mid-market stores. You use BigCommerce as your commerce backend and build your frontend in Next.js, Gatsby, or a CMS like Contentful.
- Cost: Plans start at $39/month (Standard) but headless setups realistically sit on the $299/month Plus or $749/month Pro tier.
- Dev effort: Medium. BigCommerce's GraphQL Storefront API is solid and well-documented.
- Lock-in level: Medium. Your frontend is portable; your catalog and order history live in BigCommerce.
- Upside: Lower entry cost than Shopify Plus. Good native B2B features if you sell wholesale.
Three Things to Check Before You Commit
Before you pick a platform, answer these three questions honestly:
1. Do you have a developer, or budget for one? Headless is not a no-code path. Even the friendliest options (BigCommerce headless, Hydrogen with a starter kit) need someone who can read API docs and debug a build pipeline. If that's not you and you can't hire it, a well-optimized traditional storefront will outperform a half-built headless one every time.
2. What's your actual bottleneck? If your conversion rate is 1.2% and your average order value is $45, your problem probably isn't your frontend architecture — it's your offer, your photos, or your email flow. Headless won't fix a marketing problem. But if your Lighthouse performance score is below 60 and you're losing mobile traffic, or you need a content experience your current theme physically can't deliver, headless addresses a real constraint.
3. What does migration actually cost? Factor in dev time, data migration, redirects, and a 30–60 day post-launch stabilization period. A realistic headless migration for a store with 500 SKUs runs $8,000–$25,000 depending on complexity. That's money you need to earn back. Model the ROI before you start.
A Quick Do-It-Today Checklist
If you're seriously evaluating headless, here are three actions you can take this week:
- Run a Lighthouse audit on your current store (free in Chrome DevTools). If your Performance score is above 75 on mobile, you may not need headless yet — optimize what you have first.
- Map your customization wishlist. Write down the five things your current platform won't let you do. If most of them are solvable with a different app or theme, headless is overkill. If they require architectural changes, it's worth exploring.
- Get one developer quote. Post your requirements on a platform like Contra or Toptal and get a scoped estimate. Real numbers will ground the decision faster than any comparison article — including this one.
Making the Call
A headless commerce platform comparison only gets you so far. The right platform is the one that matches your technical resources, your growth trajectory, and the specific friction you're actually feeling — not the one with the best marketing or the most GitHub stars.
If you're on Shopify and hitting performance walls, Hydrogen is the lowest-risk path. If you want zero platform fees and have a developer, Medusa or Vendure will serve you well. If you're selling internationally across three markets, Commerce Layer is worth the monthly cost. And if you want a SaaS backend without Shopify's price tag, BigCommerce headless deserves a serious look.
You don't need to pick the most sophisticated option — you need to pick the one you'll actually finish building. Start with the audit, write down your real blockers, and go from there. You've already done harder things than this.
