Frappe Helpdesk is an open-source ticketing system that pulls email, form, and portal requests into one shared queue with SLA tracking and assignment rules.
Zendesk is built for support as a function with headcount, shifts, and service level agreements, rather than for a founder answering email. Routing, macros, and SLA policies are the substance of it.
