Grafana Loki Has a Free Log Aggregation System That Won't Bankrupt You

Elasticsearch is the default choice for log aggregation. It is also expensive, resource-hungry, and complex to operate. Grafana Loki is the anti-Elasticsearch : it indexes only labels (not full text), stores logs in cheap object storage, and runs on a fraction of the resources. Why Loki Wins on Cost Elasticsearch Loki Indexing Full-text (expensive) Labels only (cheap) Storage Hot SSD required S3/GCS/MinIO RAM per GB logs ~2-4 GB ~0.5 GB Operational complexity High (shards, mappings) Low (just labels) Monthly cost (1TB logs) $500-2,000 $50-200 Getting Started 1.
