Shopify App Development

When no Shopify app in the marketplace does exactly what you need, we build it. Our Shopify app development service ships public or private apps in Node.js or Rails with the Polaris design system, embedded in the merchant admin and using GraphQL Admin API for performance.

Why this matters
  • Public (App Store) or private (custom) apps
  • Polaris UI matching the Shopify admin exactly
  • GraphQL Admin API + webhooks for real-time sync
  • Metaobject and metafield extensions
  • Full billing API integration for subscription apps

When a custom app is the right move

Custom apps make sense when: (1) a marketplace app costs more than a custom build over 24 months, (2) you need features no app provides, or (3) you're building an app you'll monetise. We help you make that call honestly in the discovery call.

Publishing to the Shopify App Store

We handle the full App Store submission process — Polaris compliance, GDPR webhook set, billing API, and the App Review checklist. Approval is typically 2–4 weeks from submission.

What's included

Polaris UI GraphQL API Webhooks Billing API App Store submission
