I lately looked at a lot of free hosting providers. And 000webhost is superior. Some others offer more space but less bandwidth, others more bandwidth and less space, some don't offer MySQL or limit queries... Surely a perfect hosting doesn't exist but please get real and don't ask too much! After all it's FREE!
A bad impression was the 6000 files limit for FTP, but then I noticed that it only limits FTP tranfers (I think for a limited period... not tested) - if you want a simpler and faster setup, use 1-click restore .
The only other problem I had was with language installation in Drupal (just disable analytics visiting

After all, all I can say is a really big
THANKS to the whole 000webhost team.
