Helpy / FreeScout

FreeScout is the super lightweight and powerful free open source help desk and shared inbox built with PHP (Laravel framework). It's the perfect help desk solution for those who need to provide professional customer support but cannot afford to pay for Zendesk or Help Scout. FreeScout is a pure open source PHP/MySQL application that can be easily deployed even on shared hosting. The platform offers unlimited agents and mailboxes with no hidden fees or user restrictions. It supports multi-channel support including email, live chat (via modules), Facebook, WhatsApp, SMS, and more.
