Grafana
The open-source standard for dashboards — query anything, visualize everything.
What is Grafana?
Grafana visualizes data from dozens of sources — Prometheus, Loki, Elasticsearch, Postgres, cloud providers — in one dashboarding layer. The surrounding LGTM stack (Loki for logs, Tempo for traces, Mimir for metrics) forms a complete open-source observability platform, with Grafana Cloud as the managed option.
Our review
4.5If a system emits data, Grafana can chart it — the data-source plugin ecosystem is the moat. Paired with Prometheus and Loki it delivers most of what commercial observability suites charge heavily for. Expect to invest in dashboard and alert hygiene; freedom includes the freedom to make a mess.
Pros
- + Connects to practically every data source
- + Full open-source stack (metrics, logs, traces)
- + Generous free tier on Grafana Cloud
Cons
- − Self-managed stack is real operational work
- − Dashboard sprawl without governance
