No per-host charges at any tier.

Grafana Cloud

Free plan Free trial

9 /10

Grafana Cloud is the hybrid open-source + managed observability platform. Free tier with limited usage across everything (metrics, logs, traces, profiles, Kubernetes, frontend, databases, synthetics). Pro from $19/month + unit-based usage ($0.50/GB logs and traces, $6.50/1k metrics series, $0.015/host hour Kubernetes). Enterprise $25,000/year minimum with volume discounts.

• Open-source foundation (Loki/Tempo/Mimir/Pyroscope) provides lock-in escape hatch
• Transparent unit pricing easier to model than Datadog SKU stacking
• Free tier genuinely useful across all services — metrics, logs, traces, K8s, frontend
