The short version

  • Each has a real cost: Home Assistant add-ons run only on Home Assistant Operating System installations, and Container installations have no access to them; Zabbix the database is the scaling limit, and high frequency polling grows history tables fast enough that untuned installations hit housekeeping stalls and query timeouts within months.
  • They diverge on capability: Home Assistant covers Local Control, Zabbix covers Agent and agentless collection.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Home Assistant

  • Add-ons run only on Home Assistant Operating System installations, and Container installations have no access to them
  • Thread and Z-Wave are controlled by add-ons, so a Container install has no out-of-the-box support for either
  • A Container installation means bringing your own Linux host with Docker and handling updates by hand
  • The recommended install path expects dedicated hardware such as a Raspberry Pi 4 or 5 with at least 2 GB of RAM, an Odroid, or an x86-64 machine
  • Every documented hardware option requires a wired Ethernet connection

Zabbix

  • The database is the scaling limit, and high frequency polling grows history tables fast enough that untuned installations hit housekeeping stalls and query timeouts within months.
  • Initial configuration is heavy; getting useful alerting rather than noise requires understanding trigger expressions, macros and template inheritance, which is a multi-week learning curve for a team new to it.
  • The AGPLv3 change at version 7.0 affects anyone offering Zabbix over a network as part of a commercial service, and that obligation is easy to inherit accidentally during an upgrade.
  • The web interface is functional rather than pleasant, and many sites end up running Grafana alongside it purely for presentation, which is a second system to maintain.
  • Upgrades between major versions touch the database schema and can take hours on large history tables, so the maintenance window is proportional to how much data you kept.

Answered from the vendors’ own pages

Home Assistant: Does Home Assistant software cost anything?

Home Assistant core software is completely free and open source. It is operated by the Open Home Foundation as a non-profit, which means it cannot be sold or acquired. Commercial products like Home Assistant hardware are sold separately.

Source
Zabbix: Is Zabbix genuinely free for commercial use?

The software has no licence fee at any scale. From version 7.0 it is AGPLv3, so offering it as a network service to third parties carries source distribution obligations.

Home Assistant: Are there paid products from Home Assistant?

Home Assistant offers official hardware products including Home Assistant Green, Connect ZBT-2, Connect ZWA-2, and Voice Preview Edition, which have separate pricing. Nabu Casa provides commercial services as an official partner.

Source
Zabbix: What is the real cost of running it?

Database administration and the person who tunes it. Budget for PostgreSQL with TimescaleDB and someone who owns the retention policy.

Zabbix: How does it compare to a commercial per-device tool?

It removes the licence line entirely and adds an operations line. Below a few hundred devices the commercial tool is often cheaper in total; above that Zabbix wins clearly.
