I want to build a membership website where users can sign up for free, after signing in they have a list of digital files they can choose to purchase, after purchasing they can download it anytime with lifetime access to it whenever they log in to their account.
What platform should I choose? wordpress plugin or something? or should I build an entire different website platform with both front and backend,
if yes what programming languages would be required to build it.
P.S – no paid alternatives please.
