Is it possible to add quota for the websites we have opened?
I am very sorry, there is currently no such feature. If there are any resources you would like to quota for?
So we don't have the opportunity to give 1G customer space for disk quota ftp
yclywz aaPanel is more of a VPS management tool and is focused on private use more than commercial. if you want to sell your hosting and looking for a free alternative, then go for ISPConfig
