runsyour server
installUpload the PHP application and run its Laravel web installer
dataMailbox, ticket and contact data in MySQL or MariaDB; attachments in application storage
the catch vs ZendeskIt is primarily an email help desk, with fewer channels, weaker reporting and automation, and paid add-on modules where Zendesk is more integrated.

dataTickets, users and messages in MySQL; attachments can be kept in the database or configured filesystem storage

dataTickets and knowledge-base data in the Frappe site database; attachments in site file storage

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.
what you give up by leaving Zendesk
- omnichannel routing, marketplace, workforce tools, reporting, compliance, and support
- omnichannel integrations
- large-scale deliverability
- AI resolution tuning
- enterprise routing and compliance
None of the picks above covers all of it. The full verdict says which gaps matter.

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.
