Quick Verdict: Grafana wins on cost, flexibility, and open-source freedom. Datadog wins on out-of-the-box completeness, unified APM+logs+metrics, and reduced operational overhead. Grafana is a visualization layer — Datadog is a full observability platform. Many teams use Grafana to display Datadog data.

Who Should Choose What?

Choose Grafana if: You want full control over your observability stack, want to minimize SaaS costs, and have engineers who can set up and maintain Prometheus + Loki + Tempo. The Grafana OSS stack is the gold standard for cost-conscious teams.
