Zabbix vs Datadog

Zabbix’s self-hosted open-source plan is free. Its homepage says there are no license fees or per-device charges, and the free plan lists unlimited monitored hosts, devices, applications, users, metrics and alerts. Managed Zabbix Cloud is also available, but its price is not published in these facts.

Datadog’s published $500 price is for AI Credits: 500 credits per month when billed annually. On-demand AI Credits cost $1.30 per credit. Those credits include Bits Chat, Bits Investigation and Bits Code; they are not a published price for Datadog’s full platform. The published pricing does not establish how the overall Datadog bill grows with hosts, telemetry volume, seats or compute. Ask Datadog for an estimate based on your expected ingestion and product mix, and confirm what the AI Credits plan covers before comparing total costs.

Zabbix says it integrates with existing systems and supports monitoring AWS, Azure, Google Cloud and more. Datadog lists integrations including AWS, Azure, Google Cloud, Kubernetes, OpenTelemetry, OpenAI and SAP. That gives Datadog a broader named set here, while Zabbix’s stated focus includes infrastructure across data centers, cloud and edge.

Neither product’s homepage details API styles, SDK language support, CLI commands or documentation coverage. Those details matter when you need to provision monitors as code, ship telemetry from a service, or automate account setup. Before adopting either, check its current API and SDK documentation for supported operations, authentication, versioning and rate limits. Also verify whether your existing agents and integration workflows work with the deployment model you plan to use. Datadog’s named OpenTelemetry integration is relevant if your instrumentation already uses that standard; Zabbix’s stated integration support is broader than the specific cloud providers it names.

Zabbix is open source and can run on your own infrastructure, including on-premises. It also offers a managed cloud service and public-cloud deployment options. Self-hosting gives your team control over where the monitoring system runs, but your team takes responsibility for operating that installation. The licence name is not published in the product facts, so confirm licence terms before redistributing or modifying it.

Datadog presents an integrated platform spanning observability, security, digital experience and software delivery. Its self-hosting options and data-export details are not published in the product facts. A wider platform footprint can mean more workflows depend on one vendor; assess that against the value of consolidating tools. Before committing, ask both vendors about export formats, retention, API access and migration paths for metrics, logs, monitors and dashboards. Those answers determine how much work a future move would involve.
