Good fit for Teams already running Prometheus/Grafana that want logs in the same UI without bringing up an ELK-class index.
Weak at Free-text search across high-cardinality fields is slower than Elasticsearch/OpenSearch — Loki indexes labels, not content.

Replaces these SaaS
- Splunk · Log management + SIEM
Use the official `loki-stack` chart or compose. Promtail (or Grafana Alloy) replaces Splunk Universal Forwarder — ship logs from your hosts. LogQL replaces SPL: `{job="app"} |= "error" | json | level="error"` is the rough equivalent of `index=app error level=error`. Visualize and alert in Grafana.
