I know there is a software for free hosting. This software forces free accounts to show ads on the pages and applies some restrictions on free accounts.

But I don't recall the software name nor the link.
can someone give me the link of this?

Also let me know if you are happy with this software?

Thanks,

Here is one...

As arche said, iPanel will probably be the best panel you will find for free web hosting.
