The short version

  • Only DigitalOcean has a free tier, so it costs nothing to try first.
  • Each has a real cost: DigitalOcean data transfer overage charged at $0.01 per GiB beyond included allowances; 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
  • They diverge on capability: DigitalOcean covers Droplets (VPS), Fly.io covers Global deployment.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

DigitalOcean

  • Data transfer overage charged at $0.01 per GiB beyond included allowances
  • Free tier includes only 3 static sites; additional static sites require paid upgrade
  • Container registry free tier capped at 500 MiB storage; exceeding requires paid tier
  • Functions free tier allows 90,000 GiB-seconds monthly; overages billed on usage basis
  • GPU Droplets require minimum monthly commitment for lower hourly rates; on-demand significantly more expensive

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
