Where each one falls short

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

Datadog Logs

  • Complex, multi-tiered pricing model based on ingestion, indexing, and storage; can become expensive at scale
  • Ingestion pricing of $0.10/GB can accumulate rapidly for high-volume logging environments

Sematext

  • The $5 Basic plan caps ingestion at 500 MB a day and retains logs for 7 days
  • Ingestion and storage are billed on separate meters, at $0.10 per GB received and $0.15 per GB stored
  • Retention is a plan property rather than a setting, so keeping logs longer means moving tier
  • The published pricing page renders Standard and Pro figures from unresolved template placeholders, so only the Basic numbers are actually readable
