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.

I love this software. We needed something free and robust for a large group of 100s of volunteers that sprung up to help tackling a big problem related to COVID-19, and you guys saved our butt. It’s been working great so far, and has just the right number of features.
