The short version

  • Only Keycloak has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keycloak requires self-hosted deployment and operational expertise to install, configure and maintain; Zabbix Cloud billed by NVPS (new values per second) rather than by number of monitored hosts, so cost scales with metric volume: Nano starts at $50/month for 50 NVPS and 2xLarge reaches $5,000/month for 10,000 NVPS

Where each one falls short

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

Keycloak

  • Requires self-hosted deployment and operational expertise to install, configure and maintain
  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions

Zabbix Cloud

  • Billed by NVPS (new values per second) rather than by number of monitored hosts, so cost scales with metric volume: Nano starts at $50/month for 50 NVPS and 2xLarge reaches $5,000/month for 10,000 NVPS
  • The free trial lasts only 5 days before a paid subscription is required
  • Annual subscription is needed to get the 10% discount; the base prices listed are monthly rates
