  • They diverge on capability: Kibana covers Data visualization, Loki covers Log aggregation.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kibana

  • Requires Elasticsearch; it is a front end for data held there rather than a standalone analytics tool
  • Self-managed means running and scaling the Elastic stack yourself
  • Cost is not Kibana's own; it follows whichever Elastic deployment sits underneath

Loki

  • The Grafana Cloud free tier caps log ingestion at 50 GB a month with 14 day retention
  • Paid log pricing is split across three separate meters, at $0.050 per GB processed, $0.400 per GB written and $0.100 per GB retained
  • Retaining logs is billed separately from ingesting them, so keeping data costs on an ongoing basis rather than once
  • The Pro plan carries a $19 a month platform fee before any usage charges
