The short version

  • Only D-ID has a free tier, so it costs nothing to try first.
  • Each has a real cost: D-ID pricing details are not published on the main pricing page; specific costs for Trial, Lite, Pro, Advanced, or Enterprise plans are not disclosed; 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: D-ID covers Photo-to-video, Fly.io covers Global deployment.
