Where each one falls short

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

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

UptimeRobot

  • Free plan is limited to a 5 minute check interval; sub-minute checking (60 seconds) requires the paid Solo plan and faster intervals (30 or 15 seconds) require Team or Scale
  • Team plan includes only 3 seats; additional seats are not covered in the base $41/$35 per month price
  • Enterprise pricing and faster-than-15-second intervals are custom and require contacting sales
