Where each one falls short

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

Airbrake

  • Data retention is 30 days on every plan, including the $799 a month Business tier
  • The entry plan at $19 a month covers 25,000 errors and 7,500 events
  • Errors beyond the plan quota are billed on demand
  • Audit logs and spike forgiveness require the Pro tier
  • The lowest tier is limited to 1 user and 1 team

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
