The short version

  • Only AutoGen has a free tier, so it costs nothing to try first.
  • Each has a real cost: AutoGen framework now in maintenance mode, no new features planned; 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: AutoGen covers Multi-agent orchestration, Fly.io covers Global deployment.
