Comparison

PromptShip vs Fly.io

PromptShip and Fly are in the same category, managed container hosting that runs your standard Docker image. Fly leans into multi-region and Machines-level control. PromptShip centers per-agent identity, production write approvals, one action ledger, and the app plus its databases as one environment.
