The short version

  • Only npm 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; npm private packages require a paid user or organization account; the free registry publishes publicly only
  • They diverge on capability: Fly.io covers Global deployment, npm covers Package installation.

  • Fly Kubernetes is a separate $75 a month per cluster
