What each one is
The product in its own terms, so the numbers below have context.
Grafana Loki
LeaderLoki 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.
OpenObserve
A cost-effective, full-stack observability solution that ingests and monitors logs, traces, metrics, and real-user monitoring data with native OpenTelemetry support. Available as a managed cloud service or self-hosted open-source deployment, using compression and columnar storage to dramatically reduce infrastructure costs.
