Shopify app development studio

Custom Shopify app development

We design and build Shopify apps and extensions for merchants who need more than off-the-shelf — internal workflows, bespoke admin tools, and integrations with ERP, CRM, PIM, subscriptions, and the rest of your stack.

Based in Copenhagen, working with Danish and international brands. English and Danish.

  • Checkout UI extensions and customer account extensions
  • Integrations with ERP, CRM, PIM, subscriptions, and logistics

  • Shopify Admin API (GraphQL), webhooks, App Bridge
  • Polaris and modern React patterns

How we work

01.

Discovery

We clarify the problem, constraints, and which Shopify surfaces (admin, checkout, storefront, APIs) are in scope.

02.

Scope & build

We agree milestones, then implement, test in dev stores, and iterate with your team.

03.

Launch & care

We help you ship safely — permissions, review if public, monitoring — and we can stay on for maintenance and new features.

Security & maintenance

Apps handle merchant and customer data: we follow least-privilege access, secure credential handling, and clear handover docs. After launch, we can agree on updates for API changes, new Shopify features, and bugfix windows.
