Hesk - Help Desk + Knowledgebase
A surprisingly simple, user-friendly and free help desk software with an integrated knowledgebase. It's a simple LAMP app though, so posting it here for everyone even if it does not get packaged. https://www.hesk.com/
Caveat: You can only "download" it; no docker images and such, so it's best suited to be installed in a folder as a LAMP application. You can see it in action at https://www.yarsahost.com/support/.
I discovered Hesk after testing dozens of other helpdesk software because according to this issue on Github, FreeScout team is not going to have any decent homepage. Custom homepage and knowledgebase come out of the box. I quite regret purchasing so many "modules" for Freescout because I decided to switch to Hesk. That's the reason why I shared it here. Cheers!
