WooCommerce vs Shopify for Mobile Apps: What UK Brands Actually Find Out

The question comes up regularly: "We are on WooCommerce. Can we still get a mobile app?"

The short answer is yes. The longer answer is that the experience of building and running a mobile app is meaningfully different depending on which platform sits underneath. If you are weighing the two up, or considering a migration partly because of your mobile ambitions, here is what the comparison actually looks like in practice.

The API question

Every mobile app built on top of an ecommerce platform lives or dies by the API. The app needs to read products, check stock, process orders, update customer accounts, and handle checkout. How cleanly the platform exposes all of this determines how much the app can do and how fast it can do it.

Shopify ships with Storefront API and the Admin API. The Storefront API is purpose-built for headless and app use cases. It handles real-time inventory checks, variant availability, customer authentication, cart management, and checkout in a single coherent GraphQL interface. It is well-documented, actively maintained, and used at scale by thousands of developers worldwide. Shopify's 2023 and 2024 platform updates doubled down on this — the Storefront API now handles subscription products, B2B pricing, and multi-currency natively.

WooCommerce exposes a REST API and, for newer setups, limited GraphQL support via plugins like WPGraphQL. The API is functional but inconsistent. Authentication is handled via application passwords or JWT tokens (plugin-dependent). Cart management is a known weak point — the REST API cart is session-based, which creates complications for mobile apps where sessions behave differently to browser sessions. Several popular WooCommerce plugins do not expose their data through the API at all, meaning features that work on your website may not be available in your app without custom development.

For an app developer, Shopify is the easier platform to build against. That translates to lower build cost, faster delivery, and fewer edge cases that need workarounds.

Hosting, uptime, and performance

Shopify hosts everything. You do not manage servers, cache configuration, or database scaling. During peak trading — Black Friday, bank holiday sales, a viral TikTok moment — Shopify scales automatically. The Storefront API response times are fast and consistent.

WooCommerce runs on WordPress, which runs on a server you or your hosting provider manages. The API performance depends on server configuration, caching setup, and database optimisation. A WooCommerce store on good managed hosting (Kinsta, WP Engine, Pressidium) will perform well. A WooCommerce store on shared hosting will not. For a mobile app making dozens of API calls per browsing session, slow API responses create a bad user experience. Customers feel it even if they cannot name it.

The checkout problem

Shopify's checkout is locked. You cannot change the HTML. What you can do is implement a fully native checkout in your mobile app via the Storefront API, using Shop Pay or standard payment flows. This is fast, familiar, and converts well.

WooCommerce checkout is fully customisable on the website, which sounds like an advantage. For a mobile app, it means the app developer needs to replicate checkout logic that exists in PHP on your WordPress server inside a native app. Payment gateways that work via WooCommerce plugins may or may not have mobile SDKs. Custom checkout fields, order bumps, and conditional logic all need to be rebuilt. This adds time and cost.

App builders vs bespoke development

There is a category of no-code Shopify mobile app builders — Tapcart, MobiLoud, Shopney, Vajro — that connect to Shopify's API and produce an app quickly. These do not exist in an equivalent form for WooCommerce. The WooCommerce app builder market is thinner, less mature, and the tools available are less polished.

If you are on WooCommerce and want a mobile app, you are almost certainly looking at bespoke development. That means higher upfront cost and a longer build timeline compared to a Shopify brand that chooses a good template builder. Against a Shopify brand that chooses bespoke development, the gap narrows — though the WooCommerce build will still typically cost more due to the API complexity described above.

Platform migration as a mobile app strategy

Some brands on WooCommerce have found that migrating to Shopify and building a mobile app in the same project is more cost-effective than building an app on WooCommerce. Migration is not trivial — product data, customer data, SEO redirects, and checkout customisation all need careful handling — but the ongoing savings in app development cost and API maintenance can justify the move.

This is particularly true for brands that have grown into WooCommerce's limitations: slow checkout pages, plugin conflicts, hosting scaling issues, or API gaps that prevent the mobile experience they want.

The honest verdict

WooCommerce and Shopify are both viable foundations for a mobile app. Shopify is the more app-friendly platform. The API is cleaner, checkout is simpler to implement natively, and the ecosystem of app developers who know the platform is larger. If your primary constraint is build cost or timeline, Shopify wins on both.

If you are committed to WooCommerce — because of existing integrations, development investment, or preference for the WordPress ecosystem — a bespoke app is possible. You will need a developer team that understands both WooCommerce's API limitations and how to work around them. Budget accordingly.
