FreeScout

open sourcewebself-hostedself-host, real ops

how to choose a Zendesk alternative

Most proven

Chatwoot, with 35,534 GitHub stars — the largest community of the 6, which usually means more answers when something breaks.

Works on your phone

Chatwoot has a mobile app on iOS and Android.

Needs real ops to self-host

Chatwoot, Zammad, FreeScout, osTicket and Frappe Helpdesk are capable but expect someone to run a server, updates and backups. Budget for that before choosing one.

why people still pay for Zendesk

People still pay for Zendesk because support software survives because missing or misrouting one customer message is expensive and every channel behaves differently. The recurring cost buys message delivery, webhooks, threading, identity, permissions, attachments, notifications, spam, search, uptime, and retention, not just the visible interface. If none of that applies to you, any pick above saves $828 a year.
