Where each one falls short

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

Coralogix

  • No self-hosted option; cloud-only SaaS requiring use of customer's AWS, Azure, or GCP infrastructure
  • Pricing is purely usage-based per GB with no flat-rate subscription option; suitable for unpredictable workloads but no cost ceiling

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
