Is it possible to customize the admin panel?

Topic summary

A developer asks whether Shopify’s admin panel can be customized or rebuilt from scratch, as their client has provided a custom design for it.

Community Response:

  • Multiple users confirm that the default Shopify admin panel cannot be modified or replaced
  • The theme editor can be customized, but not the admin interface itself
  • Building an external app to replace admin functionality is not a viable alternative

Potential Solution Identified:
Another participant references Shopify’s developer documentation on Admin Actions and Blocks, which allows limited customization of admin UI in specific areas:

  • Customer detail pages
  • Order detail pages
  • Product detail pages

Outstanding Issues:

  • The Admin Blocks feature only works in preview/dev mode
  • Attempts to deploy the app to production resulted in errors
  • Unclear how to move from preview to live deployment on an actual store

Hello.

I’m new to Shopify and my client would like me to build a custom Shopify admin panel. They even provided the design for it. Is this even possible? Can the default Shopify admin panel be customized or built from scratch?

If this is not an option, is there a way to build a full page app or something similar, that would mimic the Shopify admin, but with customizations that the client demands?

Any other suggestions are welcome.

Thanks in advance.

HI @bojans_91

No we cant change admin panel,

You can only customize theme editor but not admin panel,

Best regard

Yeah, I figured as much.

Are there other ways to make this functionality? Maybe with an external app that does the admin work instead of the Shopify admin?

Thanks

Sorry but we dont have any permission to change shopify admin at all.

Excuse me sir,
I checked the shopify dev docs and found it.
https://shopify.dev/docs/apps/admin/admin-actions-and-blocks/build-an-admin-block
These docs say we can customize the Admin UI in customer detail, order detail and product detail. But when I tried to deploy this app, I got an error.
I rechecked the docs and it says, this app just work on dev preview, so what is the purpose of this app when just working on preview mode? And how can I deploy it to my store, not preview?

Thanks in advance
