There is no free entry plan, so an agent needs a paid account before its first call.
Can an agent buy this on its own?
A price is only half the question. The other half is whether software can get from landing on the site to making a paid call without a person, which is what the AgentReady measures under adopt.
For Fly.io, it can create an account itself.
Against that, a sales call gates access; the signup flow assumes a human at a browser; credentials must be minted by hand in a dashboard. Each of those is a point where an unattended run stops and waits for a human.
That works out to 55/100 on adopt, against 53/100 overall.
What you are paying for
Fly.io provides real hardware-isolated Linux computers (called Sprites and Machines) for agents, evals, and tools, with a pay-as-you-go model where billing goes to zero when not in use. The platform specializes in running AI agents, coding agents, personal agents, MCP servers, and untrusted code in isolated VMs with persistent storage and automatic checkpointing.
