If you need a help desk that you can self-host then FreeScout is one of the best you can use. It has almost all the features that you can expect from a Zendesk alternative. You just host it somewhere and then start using it. I really liked its interface and the features that it offers. The push notifications are nice and you can have unlimited mailboxes here and assign them to any user you want. So, if you are looking for a free Zendesk ot HelpScout alternative then you are at the right place.

You guys are creating a really nice platform and its code is very well written… I really do like the whole thing. In fact being that I have used many ticket systems this one is seriously the most clean and easy to use as well as very versatile and fast with minimal upkeep and requirements.
