Datadog Free Plan: 5-Host Limits
Infrastructure monitoring for up to 5 hosts
Yes. Datadog's Infrastructure Free plan costs $0 and supports up to five hosts with one day of metric retention. The current pricing table allocates five containers per host, 100 custom metrics per host, and 500 custom events per host. It also includes standard infrastructure metrics and events, out-of-the-box dashboards, and unlimited alerts, but it is not a free bundle of every Datadog product.
What is included in Datadog Infrastructure Free
Datadog sells many products separately, so the word Free needs a product qualifier. The verified $0 offer is the Infrastructure Monitoring Free plan. It collects and visualizes core infrastructure telemetry for up to five hosts and retains metrics for one day. Per-host allowances include five containers, 100 custom metrics, and 500 custom events. Standard metrics and events, integration dashboards, and unlimited alerts are included. Features and retention sold under Logs, APM, Database Monitoring, Real User Monitoring, and other Datadog products should not be assumed to be included merely because the Infrastructure plan is free.
| Host limit | Up to 5 hosts |
|---|---|
| Metric retention | 1 day |

| Custom metrics | 100 per host |
