Grafana Loki
Cost-efficient log aggregation that indexes labels, not full text.
86
sovereigntyLoki, from Grafana Labs, keeps log storage cheap by indexing only metadata labels instead of full text, and pairs with Grafana for querying and dashboards. It is a lightweight, low-cost way to centralize logs when you don't need Splunk's full SIEM surface.

What it does well
- +Very cost-efficient storage via label-based indexing
- +Integrates natively with Grafana dashboards you may already run
- +Simpler to operate than a full search cluster
Where it falls short
- −Label-only indexing makes ad-hoc full-text search slower than OpenSearch or Splunk
- −No built-in security-analytics/SIEM layer
- −AGPL-3.0 network copyleft matters if you offer it as a service
