Will My Custom-Designed Embedded App Be Rejected If It Doesn’t Follow Shopify’s Design Aesthetic?

Shopify Apps

Topic summary

A developer is building a Shopify embedded app with a custom, visually rich UI featuring multiple colors, gradients, and a brand-driven design system—deliberately not using Shopify’s recommended Polaris design system.

Key concerns:

  • Risk of App Store rejection due to non-conformance with Shopify’s minimalistic design aesthetic
  • Whether strict visual design requirements exist for embedded utility/productivity apps (not sales channel apps)
  • Possibility of obtaining pre-validation or design feedback from Shopify before completing development

App characteristics:

  • Functions as an embedded app within Shopify admin
  • Properly implements App Bridge
  • Follows good UX practices
  • Utility/productivity tool (not a sales channel)

The developer seeks guidance from those who have successfully published apps with custom (non-Polaris) designs to avoid investing significant effort into a potentially rejectable submission. The discussion remains open with no responses yet.

Hey everyone,

I’m currently building a Shopify embedded app, and I have a question regarding the design review and approval process for publishing on the Shopify App Store.

I understand that Shopify recommends using the Polaris design system to ensure a seamless and consistent experience within the admin dashboard — which makes sense for apps that aim to blend in closely with Shopify’s native interface.

However, I’ve taken a different direction.

About my app:- I’m building a visually rich and modern UI with multiple custom colors, gradients, and components.

  • The overall design does not follow Shopify’s typical minimalistic or monochrome UI style.

  • I’m using a completely custom design system — not Polaris — because my app’s experience is meant to feel creative and brand-driven.

  • The app still works as an embedded app inside the Shopify admin, uses App Bridge properly, and follows good UX practices — but it looks and feels very different from Shopify’s native design.

  • It is not a sales channel app — it’s a utility/productivity tool used entirely within the Shopify admin.

My concerns:- Will my app get rejected during the app store review because it doesn’t follow Polaris or Shopify’s design language?

  • Are there any strict visual design requirements for embedded apps that are not sales channel apps?

  • Is there a way to get feedback or pre-validation from Shopify before I finish the entire app, just to be sure I won’t be rejected due to the design?

I’m putting a lot of time and effort into building something polished and high-quality, but I don’t want it to be rejected just because it looks different.

Any official guidance or insights from devs who’ve published apps with custom UI (not Polaris) would be really helpful!

Thanks
