Still have a question about custom shopify apps?
hello@proscube.comYes. We build custom (private) apps tailored to a single store’s workflow, as well as public apps for the Shopify App Store.
Almost anything Shopify’s APIs allow — custom admin tools, automated workflows, checkout customizations, integrations with external systems, and merchant-facing features off-the-shelf apps do not offer.
Yes. For public apps we handle billing, the listing, and the App Store review and submission process.
We build with the latest Shopify APIs, Polaris, Shopify Functions, and Remix/Node, following Shopify’s current app best practices.
