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.

Congratulations guys on this great app! After a long time searching and testing a lot of apps/plugins to give my users a great Customer Support, I’m glad I found FreeScout. Well done guys, looking forward to more awesome features and modules.
