The short version

  • 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; Sendible advertised starting prices per workspace understate typical cost, since real usage across multiple profiles quickly pushes buyers into higher tiers.
  • They diverge on capability: Fly.io covers Global deployment, Sendible covers Workspaces.

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

Sendible

  • Advertised starting prices per workspace understate typical cost, since real usage across multiple profiles quickly pushes buyers into higher tiers.
  • Assignment and approval workflows are withheld from the entry-level Core plan, limiting it to solo or unmanaged use.
  • Custom branded client reports require at least the Premium tier, adding cost for agencies that need white-labeling early.
