Server status - Simple, modern looking server status page with administration, that can run even on shared webhosting. More features are currently developed.
It is made to be run on any shared webhosting without any problems as it was written exactly for that purpose. Because why waste your money on another server (or host on a server that you might want to do maintenance on), when you can use cheap webhosting?
Installation is pretty straightforward unlike other software - just give important info to the wizard and you're good to go.
