Grafana Loki Has a Free API: Like Prometheus, But for Logs

Grafana Loki is a horizontally scalable, highly available log aggregation system. Unlike Elasticsearch, it only indexes metadata (labels), making it cost-effective to operate at scale. What Is Loki? Loki is designed to be very cost-effective and easy to operate. It does not index the contents of the logs, but rather a set of labels for each log stream — like Prometheus does for metrics.
