// EDITOR'S TAKE
Zammad is the closest to classic Zendesk ticketing, with SLAs, email threading, agent queues and a knowledge base, and it is the safest pick if your team lives in a ticket list all day. Chatwoot is stronger on live chat and social inboxes but thinner on formal ticket workflow, and frappe-helpdesk only really pays off if you already run the Frappe stack.
