“Shopify vs Magento” is usually typed by someone who wants a winner. Our benchmark scanned 80,000 live stores, 20,000 on each of four platforms, two of them Shopify and Magento, and it does not produce one. The reason is the useful part. These are not better and worse versions of the same thing. They are opposite answers to a single question: how much of your store’s technical outcome do you want to own? Shopify answers “as little as possible.” Magento answers “as much as you can handle.” If you want the platform to own the technical result, that points to Shopify; if you want to own it yourself, and can staff that, Magento. The performance, the SEO, the security, and the cost are all downstream of that one difference.
It is not which is better. It is who owns the result.
The cleanest way to see the difference is the shape of each platform in the data, not its average score. Shopify stores cluster in a narrow, high band: the tenth-percentile store scores 81.3 and the ninetieth scores 89.2, a spread of under eight points. Magento is the widest distribution in the study. Its floor is 51.2 and its ceiling is 93.5, more than forty points apart.
Read that as two different machines. Shopify hands every merchant the same managed foundation and makes it hard to fall far below it or climb far above it. Magento hands you a framework and a set of switches, most of them off, and lets your team decide where you land. A well-built Magento store scores higher on these signals than almost any Shopify store in the benchmark, because 93.5 is the highest ceiling in the study. A neglected one sits lower than any Shopify store would. On Shopify, the platform largely determines the result. On Magento, you do.
That spread is also why Magento’s lower average is easy to misread. A low baseline on a framework built to be implemented by specialists is not an inferior product; it is an unfinished one. The score measures how stores were left, not what the platform can do. One caveat sits underneath the ceiling figure, too: the scan captures headless and decoupled builds poorly, and those are most common at the sophisticated end of Magento, so if anything the real ceiling is understated here rather than inflated.
Performance: a foundation you inherit, or one you tune
Shopify’s appeal is that the technical foundation is already decided. The infrastructure is managed, the CDN is on, the base theme is quick, and Shopify had the fewest server-response-time problems of any platform we measured. You inherit a healthy starting point without configuring anything.
The constraint is the same fact from the other side: you cannot reach into the parts Shopify owns. When a Shopify store is slow, it is rarely the platform; it is the layer you control, the apps and scripts stacked into the theme. We walk through that pattern in why a fast platform still ships slow stores. You give up the ability to tune the foundation in exchange for never having to.
Magento gives you the foundation Shopify keeps to itself. You can change the stack, the caching, the rendering, the checkout, the catalog logic, all of it. That is why complex and high-volume merchants run it, often as Adobe Commerce, and it is why the ceiling is the highest in the study. The cost is that the platform configures very little for you. Full-page caching and other performance levers exist but ship off, which is why so many Magento stores show caching and response-time issues that have nothing to do with the platform’s capability and everything to do with setup. We cover the Magento side of that separately. The work is the price of the ceiling.
SEO and design: defaults versus levers
The same divide runs through the everyday categories.
On design signals, Shopify’s themes ship cleanest of any platform we measured, while Magento’s design health lands wherever the theme and build you choose put it. On SEO the gap is sharper and more revealing. Shopify stores are among the cleanest out of the box because the platform sets sensible defaults, while Magento has the deepest SEO controls of the four platforms and also the lowest clean-SEO score, because those controls ship switched off. Canonicals, sitemaps, and structured data are all configurable and frequently left at defaults that do not serve a store well. The pattern holds everywhere: the platform is capable, the defaults are conservative, and the gaps are configuration left undone rather than the framework falling short. We walk through both sides in the platform SEO pieces, for Shopify and for Magento.
Security is owned differently, not measured the same
It is tempting to compare security scores directly. You cannot, cleanly. Magento scored well on the security signals we could see, but Shopify’s server layer, where a large share of real breaches happen, is not yours to misconfigure or ours to scan. The two platforms are not measured on the same surface, so a side-by-side number would mislead.
The honest comparison is about responsibility, not score. On Shopify, most of the security surface is the platform’s job. On Magento, a substantial part of it is yours: exposed admin paths and sensitive files were among the more common issues we found on self-hosted stores, and they are habits of deployment, not flaws in the framework. We covered that exposure surface in the admin-panel piece. It is the same tradeoff as everywhere else, in security form. Simplicity hands the responsibility to the platform; control keeps it.
The cost of the model you choose
Neither model is free, and the costs differ in kind. Shopify’s cost is recurring and subscription-led: platform fees, app and transaction fees that grow with volume, and, at the Plus tier, a platform fee that scales with sales once volume passes a threshold. It is largely predictable, but not fixed, and not fully tunable to your own economics. Magento’s cost is people: the developers or agency to configure it, maintain it, and keep it current. Over the life of a store, that labour is usually the larger part of what ownership costs. A platform that scores well in the abstract is still the wrong store for you if you cannot staff the model it assumes.
So the questions that decide it are not really about Shopify or Magento. Do you have, or will you pay for, a team to own the technical outcome? How much of your store’s behaviour do you genuinely need to control, versus want to? Are you optimising for a predictable result you inherit, or the highest result you can build? Answer those honestly and the platform tends to choose itself.
Where this fits, and how to see your own numbers
This is one slice of a wider picture. If you are weighing more than these two, the full four-platform comparison and the tradeoff that runs through all of them is in the platform decision guide, and the methodology behind every figure here is in the benchmark itself.
The benchmark describes the average store on each platform, and the store you run, or one you are considering taking over, is not the average. If it already exists, the same checks that produced these numbers will show you where it actually sits, on either platform.
