Free alternatives to Zendesk

A proper support inbox with chat, email and a help center; free software, billable server chores.

Versus paying: It has less mature enterprise reporting, administration, marketplace integration and support operations than Zendesk, while self-hosting adds upkeep.

Setup: Hosted signup or Docker Compose

Watch for: Self-hosting requires a VM or Docker, PostgreSQL, Redis, SMTP, persistent or object storage, HTTPS, backups and upgrades

Tickets, SLAs and a knowledge base in a clean Frappe shell; the five-minute installer still leaves you the pager.

Versus paying: It is younger and narrower in channels, reporting, marketplace integrations and enterprise administration than Zendesk.

Setup: Frappe Cloud signup or easy-install script, Bench or Docker

Watch for: Self-hosting requires Frappe Bench or Docker, MariaDB and Redis services, mail, a domain, backups and upgrades

Email becomes an assigned team inbox with notes and collision warnings; the nicer modules open a wallet.

Versus paying: It is primarily an email help desk, with fewer channels, weaker reporting and automation, and paid add-on modules where Zendesk is more integrated.

Setup: Upload the PHP application and run its Laravel web installer

Watch for: PHP and a web server, MySQL or MariaDB, cron, IMAP or SMTP or OAuth, backups and separately paid modules for several extras

Email and web forms become assigned tickets; dated, dependable and very much your PHP server.

Versus paying: Its interface and workflows are dated and its automation, reporting, channel coverage and integration ecosystem trail Zendesk substantially.

Setup: Upload the release archive to a PHP and MySQL web server and run the installer

Watch for: PHP, MySQL, web-server permissions, inbound and outbound mail, cron and backups

A serious ticket desk with email, chat, SLAs and a knowledge base; setup is the first ticket.

Versus paying: It is a serious desk but has a smaller marketplace and reporting ecosystem than Zendesk and a heavier self-hosted stack to operate.

Setup: Hosted signup or Docker Compose, Portainer or OS package

Watch for: Self-hosting normally means Docker plus PostgreSQL, Redis, Elasticsearch or OpenSearch, mail channels, a domain and backups

A real hosted ticket desk for unlimited users, as long as Helpdesk is your one free Odoo app.

Versus paying: It has less mature omnichannel support, reporting, marketplace integration and enterprise administration than Zendesk.

Setup: Hosted signup

Watch for: None for Helpdesk alone; installing another Odoo app ends the one-app-free arrangement

Live chat, tickets, email, and a help centre for zero dollars; the tiny tawk.to badge pays the rent.

Versus paying: Its ticketing, SLA, reporting, workflow and integration depth are much lighter than Zendesk's.

Setup: Hosted signup plus a JavaScript snippet or CMS plugin

Watch for: The website widget or plugin must be installed; removing tawk.to branding is paid

A modern email-and-live-chat desk in one compact stack, because apparently that was allowed.

Versus paying: It is young and compact, with much less channel depth, reporting, marketplace integration and enterprise administration than Zendesk.

Setup: Docker or prebuilt binary with PostgreSQL

Watch for: Docker or a binary plus PostgreSQL, mail channels, a domain, HTTPS, persistent storage and backups
