△No Grafana Cloud Alerting with unified alert management
△No managed Synthetic Monitoring from global probe locations
△No Grafana OnCall managed integration for incident response

Switching Cost

Grafana Cloud has the lowest lock-in of any observability platform because every component is open source. Grafana, Prometheus, Loki, and Tempo all self-host with Docker or Helm. Your dashboards export as JSON and import directly. The migration is purely operational: you're taking on the infrastructure burden of running these services yourself. Solo devs can self-host in a few hours. Teams need to plan for high-availability Prometheus, log retention in Loki, and trace storage in Tempo. The hidden cost is scale: Grafana Cloud handles the operational complexity of running these at scale, and that expertise takes time to develop in-house.

Open observability and data visualization platform

Grafana turns data that lives somewhere else into dashboards and alerts. Prometheus, Loki, Postgres, CloudWatch: it queries each source where it sits, even several in one graph.

Prometheus Operator creates/configures/manages Prometheus clusters atop Kubernetes

Prometheus Operator turns the fiddly job of running Prometheus on Kubernetes into something you declare instead of hand-wire. Prometheus is the default open source metrics system, and the pain has always been the setup.

Building Blocks

Grafana Cloud is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
