License: AGPL-3.0 — Grafana, Loki, Tempo, Mimir all moved to AGPL-3.0 in 2021; Enterprise versions remain commercial.

Good fit for Teams that already have Grafana expertise and want best-of-breed components rather than a single product.

Weak at Operational complexity — four components to run instead of one; gluing dashboards takes a week vs SigNoz's defaults.

Replaces these SaaS

  • Datadog · Observability (metrics + logs + traces + APM)

    Replace Datadog agent with Grafana Alloy (or vendor-neutral OTel collector). Metrics go to Mimir, logs to Loki, traces to Tempo. Each Datadog dashboard maps to a Grafana dashboard; PromQL/LogQL replace Datadog's query syntax. Plan a week for dashboard parity.

  • New Relic · APM / observability platform

    Use the `docker-otel-lgtm` reference stack from grafana.com/blog. Apps export OTLP to Grafana Alloy (the collector); Alloy fans out traces to Tempo, logs to Loki, metrics to Mimir. Build dashboards in Grafana — the New Relic NRQL queries don't port, but standard PromQL + LogQL + TraceQL gets you to similar visualizations.
