The top Shopify app development companies in 2027 are HulkApps, a Chicago based Shopify agency that publishes a large portfolio of public apps, Uncap and Praella for custom apps inside Shopify Plus builds, and Folio3 for custom B2B and integration apps. Codal, Atwix, Mobikasa, CartCoders, Netalico and Storetasker complete the list for enterprise engineering, budget builds, app management and finding freelance app developers.
You need an app developer when an off the shelf app cannot handle a workflow, when you want to integrate Shopify with another system, or when you plan to sell an app on the Shopify App Store. Since January 2026, new custom apps are created through Shopify’s Dev Dashboard and installed with a direct link, so choose a team that keeps current with Shopify’s app platform.

One Check Worth Making
Before you commission a custom app, confirm that no existing app or Shopify Function already solves the problem. If you do build, agree who hosts and maintains the app, who owns the code, how API version updates will be handled and what happens if the developer stops supporting it.
Frequently Asked Questions
How much does it cost to build a Shopify app?
Simple custom apps can cost a few thousand dollars, while complex integrations and public apps built for the Shopify App Store often cost tens of thousands of dollars or more, plus hosting and maintenance.
What is the difference between a custom and a public Shopify app?
A custom app is built for one store or organisation, while a public app is listed on the Shopify App Store for many merchants and must pass Shopify’s review.
Do I need a Shopify app or a theme customisation?
If the change is visual or on the storefront, theme work or theme app extensions may be enough. Apps are needed for back office logic, integrations and features that run outside the theme.
How are new custom Shopify apps created in 2026?
Since January 2026, new custom apps are created through the Shopify Dev Dashboard and installed on a store via a direct installation link. Existing custom apps keep working.
Who maintains a custom Shopify app?
Agree this before you build. Most agencies offer maintenance retainers to handle API version changes, hosting and fixes.
