Where can I get free hosting?

Free web hosting, hmmm... most of them are scams, they have an organized way of scamming that you wont even realized you are being scammed

and by the time you have most of your files, db, and other documents on their server, they will suddenly delete your account(no back up), if you however backup, you are ok, but you risk exposing your data to untrusted platforms,

if you are starting up any application or site for a cause, free webhosting is not the way to go. as a brother's keeper,

i would advice you to host your sites where you will have peace of mind.
