In short: Netdata is ranked #1 of 28 as of 4 October 2026, ahead of openITCOCKPIT and Checkmk. The best-ranked option with a free plan is openITCOCKPIT. The lowest first paid tier on this page is openITCOCKPIT at €0.08/mo.
Keeping an eye on infrastructure calls for matching monitoring coverage to the systems you need to observe. The ranking compares agentless monitoring and deployment models alongside OS coverage, included hosts, metrics retention, service monitoring, and VM monitoring. Netdata and Zabbix lead, followed by Checkmk; Azure Monitor and Icinga are also among the first entries. Use those coverage details to compare how each tool fits your environment, and check whether a free plan is available and what the paid-from price is. The relevant balance depends on the hosts, services, and virtual machines that matter to your operations.
28 infrastructure monitoring ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
