Editorial take
Why it stands out
Grafana Mimir should be positioned as a metrics backend choice and long-term storage layer, not just as generic monitoring software.
Loading
Tool profile
Open-source, horizontally scalable, multi-tenant long-term storage backend for Prometheus metrics with a clear managed route through Grafana Cloud Metrics.
Prometheus long-term storage
Grafana Mimir deserves a place in the database because it is one of the most relevant metrics backends for teams building serious Prometheus-scale infrastructure. The official Grafana page positions it as open-source, horizontally scalable, highly available, multi-tenant long-term storage for Prometheus metrics. That is a very concrete role in modern stacks. Mimir is not generic monitoring software. It is a backend choice for teams that need durable, large-scale metrics storage and query capability without abandoning Prometheus-compatible workflows.
Its pricing story is also better than many open-source backend projects because the managed route is public and legible. The software itself is open-source and free to adopt. For the managed path, Grafana Cloud Metrics currently shows a free tier limited to 10k active series per month, a Pro tier at $6.50 per 1k series plus a $19 monthly platform fee, and Enterprise pricing as low as $3 per 1k series with a $25,000 annual minimum commit. That makes Mimir especially editorially useful because buyers can compare both OSS adoption and the managed scale path on the same official surface.
