Frequently asked
Zabbix alternatives FAQ
- Is Zabbix free?
- Yes. Zabbix is 100% open source with no licence fee, no per-device charge, and no host cap. You self-host it or run it on Zabbix Cloud. The vendor makes its money from optional support subscriptions and professional services, not from the software itself.
- How much does Zabbix support cost?
- Zabbix support subscriptions are billed annually and priced by response coverage rather than by host count. Silver starts at EUR 245 or USD 325 per month with 8x5 support and a one-day response, Gold at EUR 660 or USD 825 per month with four-hour response, and Platinum and Enterprise tiers are custom-quoted with 24x7 coverage.
- What is the best Zabbix alternative?
- Checkmk is the closest commercial alternative if you want a large maintained check catalogue with vendor support. LibreNMS and Observium are the alternatives for teams whose focus is network gear rather than servers and applications, and Prometheus is the alternative for cloud-native metrics pipelines.
- Does Zabbix have a cloud version?
- Yes. Zabbix Cloud is a fully managed SaaS platform that the vendor describes as deployable in about 60 seconds, with a free trial available. The self-hosted edition remains fully open source and unlimited, so the cloud option is a convenience rather than a requirement.
