Magento, now Adobe Commerce in its paid version, and Shopify both run serious stores. The difference is who carries the platform. On Magento, you do. On Shopify, Shopify does.
That one difference explains most of the rest.
Who runs it
A Magento store needs servers, caching, search, security patches and someone who knows how they fit together. Adobe Commerce Cloud takes some of that off you, but your team still owns the code and the deployments.
Shopify runs all of it. There are no servers to size before a sale and no patch to apply on a Friday night. You give up control of the platform in exchange for never maintaining it.
Where custom code lives
Magento lets you change almost anything in PHP, inside the platform. For a team with strong developers, that freedom is the reason they chose it.
Shopify does not let you change the core. Custom logic lives in apps and Shopify Functions, beside the store. Some things you could do on Magento are not possible. What you can build is small, separate and easy to read.
Upgrades and extensions
This is the cost most Magento merchants feel. Each upgrade is a project: test every extension, fix what broke, deploy. Extensions from different vendors can conflict, and the conflict often shows up only after an upgrade.
Shopify has no upgrade project. Apps run beside the store, not inside its code, so one app cannot break another the same way. Apps can still slow a store down, which is a different problem and a fixable one.
Checkout
On Magento, the checkout is your code. You can change every step, and you also own every bug in it.
On Shopify, the checkout is Shopify's. It is fast, and shoppers already trust it. On Shopify Plus you can extend it with checkout extensions and Functions, but you cannot rebuild it from scratch.
When to stay on Magento
Moving is not always right. Stay if most of these are true:
- Your store depends on custom logic deep in the platform, and it produces most of your revenue.
- You have a strong in-house PHP team that keeps the platform healthy.
- You run many very different stores from one install, and that setup works for you.
When Shopify is the better fit
- Upgrades, patches and hosting take more of your budget than new features.
- Extension conflicts slow down every release.
- Your team wants to change the store without a developer each time.
- Your version of Magento is close to the end of its support.
