The short version

Each has a real cost: Porter pricing based on vCPU and memory can be expensive for small projects; 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: Porter covers Rapid deployment, Fly.io covers Global deployment.
