Magento vs Shopify Plus: A Developer's Comparison

Most comparisons between Magento and Shopify Plus are written for merchants and focus on pricing, apps and how easy the admin is. This one is about what changes for the people who build and maintain the store. I work mostly with Magento, so read this with that in mind, but the goal here is to describe the trade offs as they are, not to pick a winner. Plans, limits and prices on both sides change often, so I leave them out and stick to how the platforms work.

The basic difference: you own the code or you extend a service

Magento Open Source and Adobe Commerce are PHP applications. You get the full source, you can change almost any behavior through plugins, preferences, observers and layout, and you run it on servers you choose, or on Adobe's cloud infrastructure for Adobe Commerce. Shopify Plus is a hosted service. You never see or change the core. You extend it through themes, apps that talk to its APIs, and a set of extension points that Shopify defines and runs on its own infrastructure.

Almost every other difference follows from this one. With Magento, nearly anything is possible, and you are responsible for everything you make possible. With Shopify, the platform limits what you can change, and in exchange it takes over hosting, scaling, security patches and core upgrades.

Customization model

Magento

You write modules. A module can add database tables through declarative schema, change any public method with a plugin, react to events, add admin grids and forms with UI components, change checkout with JavaScript mixins and layout, and expose new REST or GraphQL endpoints. The available tools are explained in plugins vs observers vs preferences.

The freedom has a cost. Heavy customization raises the effort of every upgrade and the risk of conflicts between extensions. A Magento store with many third party modules and deep core changes can become expensive to maintain, and that is usually the real pain point behind a replatforming discussion.

Shopify Plus

You build themes in Liquid with JSON templates and sections, apps that use the Admin and Storefront APIs, and extensions that run inside Shopify: checkout UI extensions for the checkout interface and Shopify Functions for backend logic such as discounts, payment and delivery customization, and cart validation. Functions are compiled to WebAssembly and run with strict limits on execution and input size.

The rule of thumb: if Shopify has an extension point for what you want, the result is stable and survives platform updates. If it does not, you work around it in an app, often with webhooks and the Admin API, or you accept the limit. There is no equivalent of a Magento plugin on an arbitrary core method.

Data model

Magento uses EAV for products, categories and customers, so you can add attributes with types, scopes and validation, and they become filterable, searchable and available in import and the API. Product types cover simple, configurable, bundle, grouped, virtual and downloadable, and you can add your own.

Shopify has a fixed product and variant model with a set of options per product. Custom data goes into metafields and metaobjects, which are typed and usable in themes and APIs. For many catalogs this is enough. Catalogs with complex configuration, many variant axes or product types that do not fit the product and variant structure need more design work on Shopify, sometimes with apps that handle bundles or configurators.

Checkout

Magento's checkout is code you own. The Luma checkout is Knockout and UI components, and alternatives like Hyvä Checkout exist. You can add steps, fields, custom totals and payment methods directly. A custom step is shown in a custom checkout step. The downside is that checkout is also where custom code breaks most often, and it is a PCI sensitive area you are responsible for.

Shopify's checkout is hosted by Shopify. Plus merchants can customize it through checkout UI extensions and Functions, within the blocks and targets Shopify provides. You cannot rewrite the flow, but you also do not maintain it, and it gets platform level improvements automatically.

APIs and integrations

Magento has REST and GraphQL APIs that cover most entities, plus asynchronous bulk endpoints. You can add custom endpoints in your own modules, and the main limits come from your infrastructure. Integrations can also run inside Magento as modules with queue consumers and cron jobs.

Shopify's Admin API is GraphQL first, well documented and versioned with regular releases and deprecations. API calls are rate limited, so integrations with large catalogs or high order volume have to be designed around those limits, often with bulk operations and webhooks. Integration code always lives outside Shopify, in an app you host or in a third party service.

Multi store, B2B and international

Magento's website, store and store view hierarchy lets one installation serve several brands, countries and languages with shared or separate catalogs, prices and stock. It is flexible and well understood, as described in multi store and multi website setup. B2B features such as company accounts, shared catalogs and negotiable quotes are part of Adobe Commerce, not Open Source.

Shopify handles international selling through Markets, with localized currencies, languages and domains on one store, and supports additional stores for separate brands or regions. B2B features are available on Plus. Whether either fits depends on how different the stores really are. Shared code across several Shopify stores is managed through theme and app deployment, while Magento shares one codebase and one database across all of them.

Hosting, performance and operations

With Magento, performance is your job. Varnish, Redis, OpenSearch, PHP-FPM tuning, MySQL tuning, CDN and frontend weight are all in your hands. A well run Magento store is fast, a poorly run one is slow, and the difference is engineering effort. Security patches and version upgrades also need planning and testing on every release.

With Shopify, hosting, scaling for traffic peaks, CDN and core security are handled. Performance work is mostly in the theme and in the apps you install, since each app can add scripts to the storefront. Developer operations become theme deployment, app hosting and API version upgrades.

Development workflow

Magento development happens in a full local environment with Docker or similar tools, a copy of the database, Composer, and a CI pipeline that compiles DI, deploys static content and runs tests. Deployments need care to avoid downtime. The tooling is mature, but there is a lot of it.

Shopify development uses the Shopify CLI for themes and apps, development stores, and Git integration for themes. There is no server to set up for the store itself. App backends are normal web applications in whatever stack you choose.

Lock in and data ownership

With Magento you have the database and the code, and you can move hosting or change anything at any time. With Shopify you can export data through the APIs, but the code built for it, themes in Liquid and Functions, does not move to another platform. That is not necessarily a problem, but it should be a conscious decision.

When each one fits

• Magento fits when the business has complex catalog structures, custom pricing and checkout logic, deep ERP integration that benefits from running inside the platform, or a need to own the full stack. It needs a development team or partner for the long term.
• Shopify Plus fits when requirements match its extension points, the team wants to spend less on infrastructure and upgrades, and the business values speed of change over full control.

Many replatforming discussions are really about the cost of maintaining a Magento store that grew without discipline. Before moving, it is worth checking whether an audit, cleanup of extensions and a lighter frontend would solve the actual problem.

FAQ

Can Shopify Plus do everything Magento can?

No. Shopify limits customization to its extension points, themes and apps. Some requirements that are simple modules in Magento need workarounds or are not possible on Shopify. The reverse is also true for operations, since Shopify handles hosting and upgrades.

Is Magento harder to maintain than Shopify?

Usually yes, because you are responsible for hosting, security patches, upgrades and extension compatibility. A disciplined codebase with few extensions keeps that effort reasonable.

How do developers customize Shopify checkout?

Through checkout UI extensions for interface changes and Shopify Functions for logic like discounts, delivery and payment customization, within the targets Shopify provides.

Which platform is better for complex B2B?

It depends on the requirements. Adobe Commerce has a mature B2B module set and full code access. Shopify Plus has B2B features too. Compare them against your actual workflows, especially pricing, approvals and ERP integration.
