Fly.io is a global public cloud platform for running full-stack and AI applications. It provides hardware-isolated VMs called Machines that boot in under a second, and Sprites which are Linux computers for agents that checkpoint their state. Customer workloads are hardware-isolated for security and can scale horizontally and vertically.

How fast do Machines boot?

Fly Machines boot in under a second and run close to your users. They can scale out to tens of thousands when traffic arrives.

What happens to Sprites when an agent stops?

Sprites sleep when the agent stops, but wake up with the filesystem, the running services and the installed dependencies right where they were. You can checkpoint before a risky change and roll back in seconds.
