It's a split decision.
Grafana is an observability platform centered on Grafana Cloud, with dashboards, telemetry analysis, incident response, and usage-based pricing. Zabbix is open-source infrastructure monitoring that teams can run on-premises, use as a managed cloud service, or deploy on public cloud platforms. Choose Grafana when shared telemetry context and a hosted observability stack fit your architecture. Choose Zabbix when you want self-hosted monitoring with no license fees and unlimited monitored hosts, users, metrics, and alerts.

02Pricing at real usage
Grafana Cloud's Free plan costs $0 and includes 10k active series per month, 50 GB per month for logs, traces, and profiles, and 14-day retention for metrics, logs, traces, profiles, and k6. Pro starts with a $19 monthly platform fee, then bills for usage above included allowances. The pricing page lists Metrics Pro from $6.50 per 1k series; Logs Pro at $0.050 per GB processed, $0.400 per GB written, and $0.100 per GB retained. Rates vary by product and usage. Enterprise requires a $25,000 annual spend commitment. Zabbix's free, self-hosted plan has no license fees and lists unlimited monitored hosts, users, metrics, and alerts. Its homepage says support pricing is fixed, but does not quote a rate. Ask Zabbix for support costs before comparing total operating spend.
03API, SDKs and integration
Grafana's stated integration path is to connect existing tools and data sources using open standards, including OpenTelemetry and Prometheus, plus hundreds of plugins and integrations. That gives teams a way to bring existing telemetry into Grafana Cloud without replacing every system. Zabbix integrates with existing systems and supports monitoring AWS, Azure, Google Cloud, and other environments. Its Zabbix 8.0 LTS homepage also highlights OpenTelemetry. Neither product description specifies API styles, SDK language coverage, authentication methods, or CLI workflows. For implementation planning, ask each vendor which API endpoints, SDKs, and command-line tools support the workflows you need. Grafana positions dashboards and visualization alongside telemetry analysis; Zabbix positions unified monitoring across IT and OT infrastructure. Both can fit an existing stack, but the documented integration details differ in emphasis: Grafana names standards and plugins, while Zabbix names cloud environments and infrastructure monitoring.
04Open source, self-hosting and lock-in
Both products identify as open source, but their product pages do not specify license identifiers or data-export procedures. Check the license for the exact components you deploy and ask about export formats before committing. Zabbix explicitly offers free, self-hosted on-premises software, as well as managed Zabbix Cloud and public-cloud deployment options. Running it on your own infrastructure gives your team control over deployment and data location, while also leaving hosting and maintenance decisions with you. Grafana describes Grafana Cloud as its hosted observability platform and emphasizes connecting existing tools through OpenTelemetry, Prometheus, and plugins. Those standards and integrations can reduce dependence on a single telemetry source, but they do not establish a specific export or self-hosting path. Confirm deployment requirements and migration procedures with Grafana if either is a deciding factor.
Questions people ask
Is Grafana like Power BI?
Grafana is an observability platform for telemetry, including logs, metrics, and traces, with dashboards and visualization. The product description does not position it as a business-intelligence product or compare it with Power BI. If you need operational telemetry views, Grafana is in that category; check your reporting requirements separately.
What are the key differences between Zabbix and Prometheus?
Zabbix is presented as a unified monitoring and observability platform for IT and OT infrastructure, with on-premises and cloud deployment options. Grafana names Prometheus as an open standard it connects to. The product descriptions do not provide a direct Zabbix-versus-Prometheus feature comparison, so verify collection and alerting requirements before choosing.
Is Zabbix still free?
Yes. Zabbix lists a free, open-source, self-hosted option with no license fees and unlimited monitored hosts, devices, applications, users, metrics, and alerts. The homepage also describes fixed support pricing, but does not quote a support rate. Ask Zabbix for that cost if you plan to buy support.
Which database is best for Grafana?
Grafana's product pages do not name a single best database. They say Grafana Cloud connects to existing tools and data sources and specifically mention Prometheus support. Choose based on the telemetry you collect and your existing data sources, then confirm the integration and retention requirements for your deployment.
