Grafana is the visualization layer most self-hosted observability stacks converge on. It is not itself a metrics/logs/traces store — it queries data sources (Prometheus, Loki, Tempo, Mimir, InfluxDB, Elasticsearch, etc.).
Pick it if: you are building a self-hosted stack and want the most mature dashboarding tool.
Skip it if: you want batteries-included (see SigNoz, OpenObserve). Grafana assumes you bring the stores.
