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

Hetzner Cloud

  • Cost-Optimized plans are shown as currently unavailable
  • The shared-resource tiers are positioned for variable usage and development rather than sustained production workloads
  • Regions are limited to Germany, Finland, the United States and Singapore, so latency to other markets is a real constraint
  • The uptime guarantee is 99.9 percent, below what the large hyperscalers offer on comparable services
  • Support is 24/7 by email, without a phone channel
