A custom app is built for one store only. A public app can be installed by any merchant and listed on the Shopify App Store.
Will you help with Shopify App Store approval?
Yes. The Premium package follows Shopify's review requirements and includes submission support until approval.
Which tech stack do you use?
Mainly Shopify's official Remix template with React, Polaris, App Bridge and GraphQL. Laravel is available on request.
Do I get the full source code?
Yes. You own 100% of the code, delivered with setup documentation.
Where will the app be hosted?
On your preferred platform (Fly.io, Render, Heroku, VPS). Hosting cost is paid by you.
Can you add features to my existing Shopify app?
Yes. Message me with your repo details and I'll review before quoting.
