| Architecture | Loki is horizontally scalable, highly available, and multi-tenant, and it indexes labels rather than the contents of log lines. | The documented Docker Compose deployment runs Rootprint, Quickwit, and Postgres alongside an object-storage bucket. |
| Deployment options | self-hosted | self-hosted |
| Free plan | Yes | Yes |
| Integrations | Official documentation lists Grafana Alloy as the recommended collector and describes OpenTelemetry, Promtail, Fluent Bit, Fluentd, Vector, Logstash and other clients. | The documentation lists Amazon Kinesis, Apache Kafka, and SQS as pull-based ingestion sources. |
Loki suits teams that need to aggregate and query application or infrastructure logs and can manage a self-hosted deployment or use Grafana Cloud Logs. Its label-based indexing and LogQL are central considerations for selecting it.
