Depends where you draw the line on "platform". There's still the old-school cPanel shared hosting types out there where you can drag and drop through a file manager. But then you usually have to pay a gatekeeper to get one, and that could be considered a platform? Highly not recommended, but get a static IP address and open a port on your home network to the internet that points to a folder you drag to would be the most open?
