CLI-first, and the closest anyone comes to the right primitive. CLI-first is not agent-first: Fly built the computer an agent works on, and hands back a fleet you operate.
The best builder in this series, and a deploy that succeeds without anything being reachable. A project you tend, when agents produce software nobody tends.
The best developer experience in this series, and it isn't really a place to put software. It's a workflow you adopt, and it starts from a repository an agent doesn't have. Then there's the bill.
The only platform in this series that was designed for small software. Every piece the job needs, machined by experts, waiting for an engineer to assemble them.
Three handoffs, two files you have to write, a registry URL you have to derive, and a Kubernetes dialect you have to learn. Counting the cost of getting one container running.
We are building an agent-first cloud: somewhere to run software where the agent that wrote it can also ship it.
