Fly.io Sprites
Fly.io Sprites provide hardware-isolated Linux environments specifically designed to run AI agents, evaluations, and tools with persistent block devices and automatic checkpointing. Sprites sleep when inactive and resume instantly with their filesystem and state intact. Features include secure egress policies, HTTPS URLs for agent-built applications, and centralized connectors for credential management without exposing API keys to the agent.
