I’ve never seen any store that doesn’t depend on apps, including mine, unless they are on hydrogen, which is also another part of Shopify that doesn’t work with theme app extensions.
I’ll take this as an admission that we’ll have to prepare for an avalanche of support requests with a simple answer: “Apps do not work with Canvas, please use a real theme instead” or to just abandon theme app extensions altogether and tell users to copy and paste our script on their website.
I took google and judgeme as an example of apps that can’t be just vibe coded by a senior programmer let alone a new merchant with a chat gpt wrapper.
