Hi, I’m new to the Shopify ecosystem, I’m a developer. I have a project that requires me to be able to display specific products per customer.
For example, if I’m not logged in, I show all products, but if I log in and my customer has a specific tag, filter the products for that customer.
I am using the basic plan, if you can suggest applications that help me solve this scenario and can be configurable, that would be great.
To show specific products based on customer tags, consider using apps like Locksmith or Advanced Product Filters
Hi @ImoralesMV 
Use the locksmith app to get setup fast, keeping in mind the ajax api will still expose data.
Backend automation is also something to do using shopify-flow, or mechanic app, etc etc to reject invalid order item & customer combinations.
See wholesale theme customizations or similar posts|tutorials as a starting point for content-gating/access-control on the online-sales channel.
Or roll a custom storefront using the storefront api, or the buy button SDKs.
ok, thanks, i will look those apps
Hello
We have lots of merchants use custom registration fields and customizable metafield namespaces to tag customers according with Customer Fields in conjunction with an app (as has already been suggested) like Locksmith.
Just throwing our hat in the ring 
I hope this helps.
