Where each one falls short

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

CloudAMQP

  • Free tier messaging limits are low: 1-2M messages/month
  • Free tier connection limits are restrictive: 20-40
  • Multi-tenant plans have queue limits (200-2,000 max)
  • Dedicated plans expensive at scale: up to $14,995-$17,495/month
  • Extra disk space add-on at $0.35/month per GB may add significant 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
  • 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
