From public App Store products to private internal tools, from theme app extensions to checkout UI — built on Shopify's own stack: Remix, Polaris and Functions.
Fully compliant with App Bridge, Polaris, OAuth, webhooks and Shopify's review requirements.
Built for your store only — bespoke workflows, ERP integrations and internal tooling without App Store constraints.
App blocks that merchants place through the theme editor, the modern Shopify 2.0 standard.
Custom fields, badges and validation inside checkout for Shopify Plus stores.
Discount, shipping and payment logic running at the edge in JavaScript or Rust.
Custom panels and actions on order, product and customer pages where your team already works.
What problem the app solves, which Shopify APIs it needs, plus performance and security requirements.
Remix, TypeScript, Polaris UI, Prisma and Postgres, wired through the Shopify CLI.
For public apps: App Bridge, OAuth and webhooks. For private: the custom logic only.
App Store submission and review for public apps, or a direct install link for private ones.
A straightforward public app runs €6,500–€14,000; complex builds with ERP integration reach €20,000+. Private custom apps typically land between €4,500 and €18,000.
If it is only for your store, private is faster, safer and less constrained. If you plan to sell it to other merchants, public gives you App Store distribution and revenue.
Shopify's official stack: Remix on Node.js, TypeScript, Polaris for UI, Shopify CLI, App Bridge, and Prisma with Postgres.
One to two weeks. First submissions rarely pass untouched — usually one or two rounds of fixes. We budget that into the timeline.
