Frequently Asked Questions

How much does a custom Shopify app cost?
A simple private app (connecting Shopify to one external system) typically costs $3,000–$10,000. A more complex app with its own UI, multiple features, and ongoing maintenance runs $10,000–$50,000+. Public apps for the Shopify App Store cost significantly more due to review requirements and multi-merchant architecture.
Do I need a custom app or can I use an existing one?
Check the Shopify App Store first — there are thousands of apps covering most common needs. You need a custom app when your requirements are unique, you need to connect to a proprietary system, or existing apps don't meet your performance or security requirements.
What technologies do Shopify apps use?
Modern Shopify apps are typically built with Node.js or Ruby on Rails, using Shopify's Polaris design system for the admin interface and the GraphQL Admin API for data access. Embedded apps run inside the Shopify admin, while some functionality uses Shopify Functions or theme app extensions.
