Why Migrate Away from Zendesk & Freshdesk Support?

Support desks charge heavily for every seat, discouraging you from giving engineering and product teams access to customer conversations. Self-hosting an open-source ticketing desk enables unlimited team seats, unified multi-channel communication (email, live chat, Telegram), and complete audit logging on your own hardware.
