Public, private and custom apps built on Shopify APIs, Functions and Extensions, from idea to App Store.

Discuss this service What's included

When no app does exactly what you need, we build one. From focused private apps that automate a single workflow to full public apps on the Shopify App Store, we handle product thinking, engineering and launch.

What we deliver

  • App scoping, UX and technical architecture
  • Embedded admin apps built with Remix, React and Polaris
  • Shopify Functions for discounts, delivery, payments and validation
  • Secure hosting, billing integration and App Store review support
  • Ongoing maintenance and API version upgrades

Proven in production

We design, build and run our own App Store app, Kolo: Bundles & Upsells, so we know what it takes to ship and support apps merchants rely on.
