The short version

  • Only Grafana has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fly.io egress is priced by destination region, from $0.02 per GB in North America and Europe to $0.12 per GB for Africa and India, so the same traffic costs six times more depending on where users are; Grafana the free tier retains metrics, logs and traces for 14 days only
  • They diverge on capability: Fly.io covers Global deployment, Grafana covers Dashboard creation.

Where each one falls short

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

Fly.io

  • Egress is priced by destination region, from $0.02 per GB in North America and Europe to $0.12 per GB for Africa and India, so the same traffic costs six times more depending on where users are
  • Stopped machines still bill at $0.15 per GB of root filesystem a month, so a paused service is not a free one
  • Volumes are billed on provisioned capacity rather than usage, at $0.15 per GB a month
  • Reservation discounts of 40% require paying a year up front, from $36 to $1,440
  • Fly Kubernetes is a separate $75 a month per cluster
  • Dedicated IPv4 addresses are $2 a month each

Grafana

  • The free tier retains metrics, logs and traces for 14 days only
  • Free is capped at 10,000 active metric series and 50 GB each of logs and traces a month
  • The Pro plan carries a $19 a month platform fee before any usage charges
  • Logs and traces are billed on three separate meters, at $0.050 per GB processed, $0.400 per GB written and $0.100 per GB retained
  • Retaining data is an ongoing charge rather than a one off, so historical data costs every month it exists
