Zabbix

Fully-featured open-source monitoring platform for networks, servers and applications, free with optional paid support subscriptions.

Visit Zabbix Alternatives

Zabbix monitors network devices, servers, VMs, cloud services and applications via SNMP, agents and API polling, with no artificial limits on hosts, metrics or users — general device and service monitoring rather than outside-in synthetic testing or deep flow analytics. The software itself is entirely free and open source with every feature unlocked; what Zabbix sells is optional vendor-backed support subscriptions (response-time SLAs, direct access to Zabbix engineers, guaranteed security fixes) plus a managed Zabbix Cloud offering. It is a common self-hosted alternative to Nagios and commercial NMS suites for teams that want a single tool covering infrastructure and application monitoring.
