In their own words
Grafana Loki
Grafana Loki is a free, AGPLv3-licensed log aggregation system for storing and querying application and infrastructure logs. It can be self-hosted on Linux or accessed through Grafana Cloud Logs plans, with API support and live log tailing. Loki scales horizontally, supports high availability and multiple tenants, and indexes labels instead of log-line contents. LogQL provides queries in Grafana or the LogCLI command-line tool. Grafana describes object-storage support for high-throughput, durable, petabyte-scale retention. Loki can evaluate alerting rules on incoming logs and send results to Prometheus Alertmanager, with native integrations for Prometheus, Grafana, and Kubernetes. Documented ingestion options include Grafana Alloy, OpenTelemetry, Kubernetes Monitoring Helm, Docker, Fluent Bit, Fluentd, and Logstash. Installation methods include Helm, Tanka, Docker, Docker Compose, local installation, and source builds. Cloud plans range from free to paid Pro and Enterprise options.
