In search of a good helpdesk (self hosted)

ArcticDesk has promise, but looks to be abandon.  As @mikho noted it's lacking in features frontend and backend.

We use Kayako intergrated with WHMCS, working great and we really love using it.

The UI of Kayako v4 is neat and pretty, It's much better and improvements are made often at least compared to osticket which I think is still outdated.
