Shopify App Development for Workflows No Marketplace App Covers
Custom apps, private apps for internal workflows, and public apps built for the Shopify App Store — our team builds against the Shopify Admin API and Storefront API, following Shopify Polaris standards, so your app is fast, secure, and merchant-friendly from day one.




































Custom App vs. Public App vs. Private App
A Shopify app development company builds applications that extend what a Shopify store can do — beyond internal app usage, this includes public App Store apps, automated workflows, and improvements to checkout, integrations, and reporting. There are three distinct categories worth understanding before you decide what to build.
Public apps are built for any merchant and listed on the Shopify App Store — think of apps like Klaviyo for email marketing or Privy for popups. Building one means designing for merchant-friendly UX, handling a billing setup, and passing Shopify's app review and approval process.
Custom apps — what Shopify used to call private apps before phasing that model out in January 2022 for security reasons — are tailor-made applications built exclusively for a single Shopify store to solve a specific operational, marketing, or integration need. They're not listed anywhere and are only accessible to the store they're built for. Custom apps are the right call when a workflow is proprietary: internal dashboards, automation tools, ERP or CRM connections, custom validation rules, discount engines, or order-routing logic.
Whichever direction fits, we build using the Shopify Admin API for backend functionality and the Storefront API for front-end interaction, following Shopify Polaris design guidelines so the app UI feels native to the Shopify admin rather than bolted on.

We've Got the Answers
Public apps are available to any merchant via the Shopify App Store. Custom apps are built exclusively for one store to solve a specific need, and are not listed publicly.
Shopify phased out the old "private app" authentication model in January 2022 for security reasons. Custom apps replaced them with the same capabilities but stronger, token-based security.
Basic apps typically start in the low thousands of dollars, scaling up with feature complexity, integrations, and whether the app needs App Store submission and billing setup. Book a call and we'll scope your specific requirement.
