What each one is

The product in its own terms, so the numbers below have context.

Grafana Loki

Leader

Loki is a distributed log aggregation platform designed for simplicity and cost efficiency. It stores logs with only label metadata indexed rather than full-text content, making it straightforward to operate and integrate with Prometheus and Grafana for unified observability.
