Grafana Loki

What is Grafana Loki?

Log aggregation system that indexes labels rather than full text, so large log volumes stay cheap.

Who is Grafana Loki best for?

Grafana Loki is best for platform teams on Kubernetes who want to store and query large log volumes cheaply.

• Kubernetes logs

  Pod labels are picked up and indexed automatically, so logs line up with the Prometheus labels you already use.

• Large log volumes on a budget

  Only labels are indexed and log lines are compressed into object storage, which keeps the index small and storage cheap.

• Grafana users

  Logs sit next to metrics and traces in Grafana, and LogQL can build metrics and alerts from log lines.

How much does Grafana Loki cost?

Grafana Loki is free to self-host; on Grafana Cloud, logs are free up to 50 GB a month, and the Pro plan costs $19 a month plus usage, such as $0.40 per GB written.

The $19 Pro platform fee covers every Grafana Cloud service, each with its own included usage. Enterprise needs a minimum commitment of $25,000 a year and offers custom retention. Full pricing on grafana.com. We checked these prices on 8 Nov 2026.
