You spent three weekends reading docs, watched a dozen YouTube demos, and you still aren't sure which headless commerce platform is actually worth your time and money. Sound familiar? I've been there — twice — and the noise around headless has only gotten louder heading into 2024.
Here's the thing: headless isn't magic, and it isn't for everyone. But if you're hitting the ceiling on your current all-in-one platform — slow page loads, rigid templates, checkout flows you can't touch — then a headless commerce platform comparison for 2024 is exactly the exercise you need before you commit a single dollar or developer hour.
Let's cut through the hype and look at what actually matters for a small or mid-size store.
What "Headless" Actually Means (Plain English)
In a traditional e-commerce setup, the front end (what shoppers see) and the back end (cart, checkout, inventory) are baked together. Change one, you risk breaking the other.
Headless separates them. Your storefront — built in whatever framework you like, React, Next.js, Astro, you name it — talks to the commerce engine through an API. The engine handles products, pricing, and orders; your front end handles the experience.
The payoff: faster pages, total design freedom, and the ability to sell on any surface — web, mobile app, kiosk, voice — from one back end. The cost: more setup complexity and, usually, a higher monthly bill or more developer time.
A store doing $20,000/month in revenue with a two-person team probably doesn't need this yet. A store at $150,000/month that's losing 18% of mobile visitors at checkout because the theme won't cooperate? That's a different story.
The Platforms Worth Comparing in 2024
I'm focusing on five options that come up most often in conversations with store owners who are seriously evaluating a switch. These aren't the only choices, but they cover the realistic range from "almost headless" to "fully composable."
Shopify + Hydrogen/Storefront API — Shopify's own headless path. You keep Shopify as the commerce engine and build your front end with their Hydrogen framework (React-based) or any framework hitting the Storefront API. Plans start at $79/month (Basic) but serious headless work usually lands you on Shopify Plus at $2,300/month or a percentage of revenue. The upside: Shopify's checkout is battle-tested and conversion-optimized. The downside: you're still inside Shopify's ecosystem for payments and checkout, which means their transaction fees apply unless you use Shopify Payments.
BigCommerce (Headless) — BigCommerce has offered headless capabilities for a few years now and it's genuinely underrated for mid-market stores. Their Catalyst starter (Next.js-based) launched in late 2023 and cuts setup time significantly. Pricing runs $39–$399/month on standard plans; enterprise pricing is custom. No transaction fees on any plan, which matters more than people realize once volume picks up.
Medusa.js — Open-source, self-hosted, and free at the core. Medusa is the answer if you want maximum control and have a developer on hand (or are one yourself). You own the infrastructure, which means hosting costs of $20–$200/month on a service like Railway or Render for a small store, scaling up from there. The community is active, the docs are solid, and the plugin ecosystem is growing fast. The trade-off is that you're responsible for security patches, uptime, and anything the core doesn't cover.
Commercetools — Enterprise-grade, API-first from the ground up. This is a true composable commerce platform: every function (cart, pricing, promotions, inventory) is a separate service. Pricing is usage-based and typically starts around $1,000–$2,000/month even for smaller implementations. If you're doing multi-region, multi-currency, or B2B with complex pricing rules, Commercetools is worth the cost. For a single-country DTC store under $5M ARR, it's almost certainly overkill.
Swell — A solid middle-ground option that often flies under the radar. Swell is API-first, supports multi-currency and subscriptions natively, and has a dashboard that won't scare off non-technical team members. Pricing starts at $299/month for growth-stage stores. It's not as mature as Shopify or BigCommerce in terms of third-party integrations, but if subscriptions or complex bundles are central to your model, it's worth a serious look.
How to Actually Compare Them (Four Criteria That Matter)
Every headless commerce platform comparison in 2024 should run through the same four filters. Here they are, with the questions you should be asking.
1. Total cost of ownership, not just the monthly fee
The platform fee is the easy number. The harder numbers are developer time, hosting, and the integrations you'll need to buy or build. A $0/month open-source platform can easily run $3,000–$8,000 in setup costs if you're hiring a developer. A $299/month SaaS might get you live in two weeks with no dev help. Run a 12-month total — platform + hosting + dev time + integrations — before you decide.
2. Checkout flexibility and conversion impact
This is where headless stores often stumble. Your beautiful custom front end funnels into... a checkout that you can't fully control. Shopify Plus lets you customize checkout with their editor and Checkout Extensibility. Medusa gives you full checkout control. BigCommerce's checkout is customizable but requires some work. Ask: can I A/B test my checkout? Can I add a post-purchase upsell? Can I change the layout? The answers vary a lot.
3. How much of the stack do you actually own?
If the platform shuts down or changes pricing, how painful is your exit? With Medusa, you own everything — migrate when you want. With Shopify Plus, your data is exportable but your checkout logic, scripts, and Hydrogen components are Shopify-flavored. There's no objectively right answer here, but you should go in with eyes open about the trade-offs.
4. Your team's real technical capacity
Be honest with yourself. Do you have a developer who can maintain a Next.js app, handle API updates, and debug a broken webhook at 11pm? Or do you have a marketing team that needs to update a landing page without filing a ticket? The best headless platform for your store is the one your team can actually operate six months after launch.
A Quick Real-World Example
A candle brand I know — about $280,000/year in revenue, two full-time staff — switched from a standard Shopify theme to a Shopify Hydrogen storefront last year. Their goal was faster page loads and a custom quiz that recommended scents based on a few questions.
Result: Core Web Vitals improved significantly (LCP dropped from 4.2s to 1.8s), the quiz launched without a third-party app fee, and mobile conversion rate climbed from 2.1% to 2.9% over the following quarter. That 0.8-point lift on $280K is roughly $22,400 in additional revenue annually.
But here's the honest part: they spent about $12,000 on a freelance developer to build and launch the Hydrogen storefront, and they pay $2,300/month for Shopify Plus now (up from $79/month). The math still works in their favor over 24 months, but it was not a cheap or fast decision. They also still rely on the developer for any significant front-end changes, which is a real ongoing cost.
That's the kind of clear-eyed math you need to do before you commit.
Three Things You Can Do Right Now
You don't have to pick a platform today. But you can make real progress this week.
Action 1: Audit your current pain points with numbers. Don't just write "checkout is slow." Write "checkout page loads in 5.3 seconds on mobile and our cart-to-purchase rate is 34%, versus an industry average of 45–50%." Specific problems point to specific solutions.
Action 2: Run a 12-month cost model for your top two options. Use a simple spreadsheet: platform fee × 12, estimated hosting, estimated developer hours × your hourly rate or a freelancer's rate, and the integrations you know you need. Compare the totals side by side. You might be surprised which one actually costs less.
Action 3: Spin up a free trial or sandbox. BigCommerce, Swell, and Medusa all let you poke around without a credit card. Shopify's Hydrogen has a demo you can fork on GitHub in about 20 minutes. Actually clicking through the admin and reading one or two API docs tells you more than any comparison article (including this one) ever will.
Picking the Right Fit for Your Store
If I had to draw a rough map: stores under $500K ARR with no dedicated developer should look hard at BigCommerce's Catalyst or stay on a well-optimized traditional setup until the pain is real. Stores between $500K and $3M ARR with one developer or a reliable freelancer should seriously evaluate Medusa or Swell. Stores above $3M ARR with a small tech team should put Shopify Plus/Hydrogen and Commercetools on the shortlist alongside Medusa.
The headless commerce platform comparison for 2024 doesn't have a single winner. It has a winner for your revenue range, your team, your roadmap, and the specific problems you're trying to solve. That's actually good news — it means the right answer exists, you just have to find it.
Start with your audit this week. You already know more about your store's needs than any vendor does. Trust that knowledge, run the numbers, and take the next step from there. You've got this.
