See what Zabbix offers for infrastructure monitoring in 2026: agent-based and agentless checks, templates, dashboards, pricing, and how it compares to rivals.
Zabbix is an open-source, enterprise-class monitoring solution built to give IT and operations teams visibility into networks, servers, cloud environments, containers, applications, and IoT or OT devices from a single platform. It was created by Alexei Vladishev, who released the first version in 2001 and founded Zabbix LLC, now based in Riga, Latvia, in 2005 to develop and commercialize the project.
The defining trait of Zabbix is that its full feature set is open source and free to use, with no separate paid tier gating core functionality. Organizations can self-host Zabbix on their own infrastructure at no license cost, or use the vendor's managed Zabbix Cloud offering for a subscription fee that covers hosting and operational overhead.
Zabbix is widely used by enterprises, government agencies, and managed service providers that need to monitor large, heterogeneous environments, thanks to its support for agent-based and agentless data collection across a wide range of protocols.
Zabbix collects metrics through a lightweight agent installed on monitored hosts, or agentlessly using SNMP, IPMI, JMX, SSH, and HTTP checks, so it can monitor devices where installing software is not practical. Templates and automatic network discovery speed up configuration across large fleets of similar servers or devices.
The platform includes customizable dashboards, graphs, network maps, and business service views for tracking infrastructure health, SLA compliance, and incident status, along with a flexible alerting engine that supports multi-step escalation chains and integrations with common notification channels.
For large or geographically distributed environments, Zabbix proxies allow distributed data collection that reports back to a central server, and a REST API supports automation, custom integrations, and programmatic configuration. Recent versions have added trend prediction and anomaly detection on top of the core time-series monitoring engine.
The self-hosted version of Zabbix is completely free and open source, with no feature restrictions, making it a common choice for organizations that want full control over their monitoring stack without licensing costs.
Zabbix LLC also offers Zabbix Cloud, a managed hosting option available across multiple capacity tiers, with entry-level pricing cited around fifty dollars per month and a free trial period for evaluation.
Separately, Zabbix and its certified partners sell commercial support subscriptions that add guaranteed response times, expert access, and long-term maintenance assurance on top of the free software, priced on a custom basis depending on environment size and support level.
